金声玉亮2.0	To solve this problem, we need to find a number that satisfies the following conditions: 1. The number leaves a remainder of 5 when divided by 8. 2. The number leaves a remainder of 1 when divided by 3. 3. The number leaves a remainder of 7 when divided by 11. This can be represented by the following system of congruences: x ≡ 5 (mod 8) x ≡ 1 (mod 3) x ≡ 7 (mod 11) To solve this system, we can use the Chinese Remainder Theorem (CRT). The CRT states that if the moduli are pairwise coprime (which they are in this case: 8, 3, and 11), there exists a unique solution modulo the product of the moduli. Let's denote: M = 8 * 3 * 11 = 264 Now, we need to find the partial products: M1 = M / 8 = 264 / 8 = 33 M2 = M / 3 = 264 / 3 = 88 M3 = M / 11 = 264 / 11 = 24 Next, we need to find the modular inverses: y1 = M1^(-1) mod 8 y2 = M2^(-1) mod 3 y3 = M3^(-1) mod 11 We can calculate these inverses as follows: y1 = 33^(-1) mod 8 = 5 y2 = 88^(-1) mod 3 = 2 y3 = 24^(-1) mod 11 = 2 Now we can calculate x using the following formula: x = (5 * 33 * 5) + (1 * 88 * 2) + (7 * 24 * 2) mod 264 x = (825) + (176) + (336) mod 264 x = 1337 mod 264 x = 241 Therefore, the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11 is 241.	205
deepseekr1	To find the smallest positive integer \( N \) that satisfies the following congruences: 1. \( N \equiv 5 \pmod{8} \) 2. \( N \equiv 1 \pmod{3} \) 3. \( N \equiv 7 \pmod{11} \) We start by solving the first two congruences. Express \( N \) as \( N = 8k + 5 \). Substituting this into the second congruence: \[ 8k + 5 \equiv 1 \pmod{3} \] Simplifying, we get: \[ 8k + 5 \equiv 1 \pmod{3} \implies 2k + 2 \equiv 1 \pmod{3} \implies 2k \equiv -1 \pmod{3} \implies 2k \equiv 2 \pmod{3} \implies k \equiv 1 \pmod{3} \] Thus, \( k = 3m + 1 \) for some integer \( m \). Substituting back, we get: \[ N = 8(3m + 1) + 5 = 24m + 13 \] So, \( N \equiv 13 \pmod{24} \). Next, we incorporate the third congruence. Express \( N \) as \( N = 24m + 13 \). Substituting this into the third congruence: \[ 24m + 13 \equiv 7 \pmod{11} \] Simplifying, we get: \[ 24m + 13 \equiv 7 \pmod{11} \implies 2m + 2 \equiv 7 \pmod{11} \implies 2m \equiv 5 \pmod{11} \] The multiplicative inverse of 2 modulo 11 is 6, so: \[ m \equiv 5 \cdot 6 \pmod{11} \implies m \equiv 30 \pmod{11} \implies m \equiv 8 \pmod{11} \] Thus, \( m = 11n + 8 \) for some integer \( n \). Substituting back, we get: \[ N = 24(11n + 8) + 13 = 264n + 205 \] Therefore, the smallest positive integer solution is \( N = 205 \) when \( n = 0 \). Verification: 1. \( 205 \div 8 = 25 \) remainder \( 5 \) 2. \( 205 \div 3 = 68 \) remainder \( 1 \) 3. \( 205 \div 11 = 18 \) remainder \( 7 \) All conditions are satisfied. The smallest positive integer is \(\boxed{205}\).	205
gpto1	To solve the problem, we need to find the smallest positive integer \( N \) that satisfies the following three congruences: 1. \( N \equiv 5 \mod 8 \) 2. \( N \equiv 1 \mod 3 \) 3. \( N \equiv 7 \mod 11 \) We will use the Chinese Remainder Theorem (CRT) to find a solution that satisfies all three congruences simultaneously. Step 1: Solve the first two congruences First, consider the congruences: - \( N \equiv 5 \mod 8 \) - \( N \equiv 1 \mod 3 \) Let’s express \( N \) in terms of \( k \): \[ N = 8k + 5 \] Now substitute \( N \) into the second congruence: \[ 8k + 5 \equiv 1 \mod 3 \] Simplify by computing modulo 3: - \( 8 \mod 3 = 2 \) - \( 5 \mod 3 = 2 \) So the equation becomes: \[ 2k + 2 \equiv 1 \mod 3 \] Subtract 2 from both sides: \[ 2k \equiv -1 \mod 3 \] Since \( -1 \mod 3 = 2 \), the equation simplifies to: \[ 2k \equiv 2 \mod 3 \] To solve for \( k \), multiply both sides by the modular inverse of 2 modulo 3. The modular inverse of 2 modulo 3 is 2 because \( 2 \times 2 \equiv 1 \mod 3 \). \[ k \equiv 2 \times 2 \mod 3 \] \[ k \equiv 4 \mod 3 \] \[ k \equiv 1 \mod 3 \] So \( k = 3m + 1 \), where \( m \) is an integer. Substitute back into the expression for \( N \): \[ N = 8(3m + 1) + 5 \] \[ N = 24m + 8 + 5 \] \[ N = 24m + 13 \] This means: \[ N \equiv 13 \mod 24 \] Step 2: Combine with the third congruence Now consider the congruences: - \( N \equiv 13 \mod 24 \) - \( N \equiv 7 \mod 11 \) Express \( N \) in terms of a new variable \( p \): \[ N = 24p + 13 \] Substitute \( N \) into the third congruence: \[ 24p + 13 \equiv 7 \mod 11 \] Simplify by computing modulo 11: - \( 24 \mod 11 = 2 \) - \( 13 \mod 11 = 2 \) So the equation becomes: \[ 2p + 2 \equiv 7 \mod 11 \] Subtract 2 from both sides: \[ 2p \equiv 5 \mod 11 \] To solve for \( p \), multiply both sides by the modular inverse of 2 modulo 11. The modular inverse of 2 modulo 11 is 6 because \( 2 \times 6 \equiv 1 \mod 11 \). \[ p \equiv 6 \times 5 \mod 11 \] \[ p \equiv 30 \mod 11 \] \[ p \equiv 8 \mod 11 \] So \( p = 11n + 8 \), where \( n \) is an integer. Substitute back into the expression for \( N \): \[ N = 24(11n + 8) + 13 \] \[ N = 264n + 192 + 13 \] \[ N = 264n + 205 \] Step 3: Find the smallest positive integer \( N \) Since \( n \) is an integer and we seek the smallest positive \( N \), set \( n = 0 \): \[ N = 264 \times 0 + 205 \] \[ N = 205 \] Answer: \[ \boxed{205} \]	205
GPT-4o	To solve the problem, we need to find the smallest positive integer \( x \) that satisfies the following system of congruences: 1. \( x \equiv 5 \pmod{8} \) 2. \( x \equiv 1 \pmod{3} \) 3. \( x \equiv 7 \pmod{11} \) We will solve this step by step using the method of successive substitutions, also known as the Chinese Remainder Theorem in an informal way. 1. Start with the first congruence: \[ x \equiv 5 \pmod{8} \] This means \( x = 8k + 5 \) for some integer \( k \). 2. Substitute \( x = 8k + 5 \) into the second congruence: \[ 8k + 5 \equiv 1 \pmod{3} \] Simplify the congruence: \[ 8k + 5 \equiv 1 \pmod{3} \] Since \( 8 \equiv 2 \pmod{3} \) and \( 5 \equiv 2 \pmod{3} \): \[ 2k + 2 \equiv 1 \pmod{3} \] \[ 2k \equiv -1 \pmod{3} \] \[ 2k \equiv 2 \pmod{3} \] \[ k \equiv 1 \pmod{3} \] Therefore, \( k = 3m + 1 \) for some integer \( m \). 3. Substitute \( k = 3m + 1 \) back into \( x = 8k + 5 \): \[ x = 8(3m + 1) + 5 \] \[ x = 24m + 8 + 5 \] \[ x = 24m + 13 \] So, \( x \equiv 13 \pmod{24} \). 4. Substitute \( x = 24m + 13 \) into the third congruence: \[ 24m + 13 \equiv 7 \pmod{11} \] Simplify the congruence: \[ 24m + 13 \equiv 7 \pmod{11} \] Since \( 24 \equiv 2 \pmod{11} \) and \( 13 \equiv 2 \pmod{11} \): \[ 2m + 2 \equiv 7 \pmod{11} \] \[ 2m \equiv 5 \pmod{11} \] To solve for \( m \), we need the multiplicative inverse of 2 modulo 11, which is 6 (since \( 2 \times 6 = 12 \equiv 1 \pmod{11} \)): \[ m \equiv 5 \times 6 \pmod{11} \] \[ m \equiv 30 \pmod{11} \] \[ m \equiv 8 \pmod{11} \] Therefore, \( m = 11n + 8 \) for some integer \( n \). 5. Substitute \( m = 11n + 8 \) back into \( x = 24m + 13 \): \[ x = 24(11n + 8) + 13 \] \[ x = 264n + 192 + 13 \] \[ x = 264n + 205 \] The smallest positive \( x \) occurs when \( n = 0 \): \[ x = 205 \] Therefore, the smallest positive integer that satisfies all the given congruences is \( \boxed{205} \).	205
llama3.1-70B-Instruct	To find the smallest positive integer that satisfies the given conditions, we can use the Chinese Remainder Theorem (CRT). The CRT states that if we have a system of congruences: x ≡ a1 (mod n1) x ≡ a2 (mod n2) ... x ≡ ak (mod nk) where ni are pairwise coprime (i.e., gcd(ni, nj) = 1 for i ≠ j), then there exists a unique solution modulo N = n1n2...nk. In this case, we have: x ≡ 5 (mod 8) x ≡ 1 (mod 3) x ≡ 7 (mod 11) First, we need to find the least common multiple (LCM) of 8, 3, and 11, which is 264. Next, we can use the CRT to find the solution. We can start by finding the solution modulo 8: x ≡ 5 (mod 8) This means x = 5 + 8k for some integer k. Now, we need to find the solution modulo 3: x ≡ 1 (mod 3) Substituting x = 5 + 8k, we get: 5 + 8k ≡ 1 (mod 3) Simplifying, we get: 2k ≡ -4 (mod 3) k ≡ 2 (mod 3) So, k = 2 + 3m for some integer m. Now, we substitute k = 2 + 3m into x = 5 + 8k: x = 5 + 8(2 + 3m) = 5 + 16 + 24m = 21 + 24m Finally, we need to find the solution modulo 11: x ≡ 7 (mod 11) Substituting x = 21 + 24m, we get: 21 + 24m ≡ 7 (mod 11) Simplifying, we get: 10m ≡ -14 (mod 11) m ≡ 4 (mod 11) So, m = 4 + 11n for some integer n. Substituting m = 4 + 11n into x = 21 + 24m, we get: x = 21 + 24(4 + 11n) = 21 + 96 + 264n = 117 + 264n Therefore, the smallest positive integer that satisfies the given conditions is x = 117.	205
llama3.1-405B-Instruct	To find the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11, we can use the Chinese Remainder Theorem (CRT). First, we need to find the least common multiple (LCM) of 8, 3, and 11, which is 264. Next, we need to find the solutions to the following congruences: x ≡ 5 (mod 8) x ≡ 1 (mod 3) x ≡ 7 (mod 11) Using the CRT, we can find the solution to the first congruence: x ≡ 5 (mod 8) x = 5 + 8k where k is an integer. Substituting this solution into the second congruence, we get: 5 + 8k ≡ 1 (mod 3) 8k ≡ -4 (mod 3) k ≡ 2 (mod 3) So, k = 2 + 3m, where m is an integer. Substituting this value of k into the solution to the first congruence, we get: x = 5 + 8(2 + 3m) x = 21 + 24m Now, we need to find the solution to the third congruence: x ≡ 7 (mod 11) 21 + 24m ≡ 7 (mod 11) 24m ≡ -14 (mod 11) m ≡ 3 (mod 11) So, m = 3 + 11n, where n is an integer. Substituting this value of m into the solution to the second congruence, we get: x = 21 + 24(3 + 11n) x = 93 + 264n Therefore, the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11 is 93.	205
DeepSeek-Coder-V2	To solve this problem, we need to find the smallest positive integer \( x \) that satisfies the following system of congruences: \[ \begin{cases} x \equiv 5 \pmod{8} \\ x \equiv 1 \pmod{3} \\ x \equiv 7 \pmod{11} \end{cases} \] We will use the method of successive substitutions to find the solution. ### Step 1: Solve the first two congruences First, consider the congruences: \[ \begin{cases} x \equiv 5 \pmod{8} \\ x \equiv 1 \pmod{3} \end{cases} \] We can express \( x \) in terms of the first congruence: \[ x = 8k + 5 \quad \text{for some integer } k \] Substitute \( x = 8k + 5 \) into the second congruence: \[ 8k + 5 \equiv 1 \pmod{3} \] Simplify the congruence: \[ 8k + 5 \equiv 1 \pmod{3} \implies 2k + 2 \equiv 1 \pmod{3} \implies 2k \equiv -1 \pmod{3} \implies 2k \equiv 2 \pmod{3} \] Since \( 2 \) and \( 3 \) are coprime, we can divide both sides by \( 2 \): \[ k \equiv 1 \pmod{3} \] Thus, \( k \) can be written as: \[ k = 3m + 1 \quad \text{for some integer } m \] Substitute \( k = 3m + 1 \) back into \( x = 8k + 5 \): \[ x = 8(3m + 1) + 5 = 24m + 8 + 5 = 24m + 13 \] So, we have: \[ x \equiv 13 \pmod{24} \] ### Step 2: Solve the combined congruence with the third congruence Now, consider the combined congruence with the third congruence: \[ \begin{cases} x \equiv 13 \pmod{24} \\ x \equiv 7 \pmod{11} \end{cases} \] We can express \( x \) in terms of the first combined congruence: \[ x = 24n + 13 \quad \text{for some integer } n \] Substitute \( x = 24n + 13 \) into the third congruence: \[ 24n + 13 \equiv 7 \pmod{11} \] Simplify the congruence: \[ 24n + 13 \equiv 7 \pmod{11} \implies 2n + 2 \equiv 7 \pmod{11} \implies 2n \equiv 5 \pmod{11} \] To solve \( 2n \equiv 5 \pmod{11} \), we need the multiplicative inverse of \( 2 \) modulo \( 11 \). The inverse of \( 2 \) modulo \( 11 \) is \( 6 \) because: \[ 2 \cdot 6 \equiv 1 \pmod{11} \] Multiply both sides of \( 2n \equiv 5 \pmod{11} \) by \( 6 \): \[ n \equiv 30 \pmod{11} \implies n \equiv 8 \pmod{11} \] Thus, \( n \) can be written as: \[ n = 11p + 8 \quad \text{for some integer } p \] Substitute \( n = 11p + 8 \) back into \( x = 24n + 13 \): \[ x = 24(11p + 8) + 13 = 264p + 192 + 13 = 264p + 205 \] So, the smallest positive integer \( x \) is: \[ x = 205 \] Thus, the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11 is: \[ \boxed{205} \]	205
Qwen2-72B-Instruct	To solve this problem, we need to find a number that satisfies the following conditions: 1. The number leaves a remainder of 5 when divided by 8. 2. The number leaves a remainder of 1 when divided by 3. 3. The number leaves a remainder of 7 when divided by 11. This can be represented by the following system of congruences: x ≡ 5 (mod 8) x ≡ 1 (mod 3) x ≡ 7 (mod 11) To solve this system, we can use the Chinese Remainder Theorem (CRT). The CRT states that if the moduli are pairwise coprime (which they are in this case: 8, 3, and 11), there exists a unique solution modulo the product of the moduli. Let's denote: M = 8 * 3 * 11 = 264 Now, we need to find the partial products: M1 = M / 8 = 264 / 8 = 33 M2 = M / 3 = 264 / 3 = 88 M3 = M / 11 = 264 / 11 = 24 Next, we need to find the modular inverses: y1 = M1^(-1) mod 8 y2 = M2^(-1) mod 3 y3 = M3^(-1) mod 11 We can calculate these inverses as follows: y1 = 33^(-1) mod 8 = 5 y2 = 88^(-1) mod 3 = 2 y3 = 24^(-1) mod 11 = 2 Now we can calculate x using the following formula: x = (5 * 33 * 5) + (1 * 88 * 2) + (7 * 24 * 2) mod 264 x = (825) + (176) + (336) mod 264 x = 1337 mod 264 x = 241 Therefore, the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11 is 241.	205
baichuan4	To find the smallest positive integer that satisfies the given conditions, we can use the Chinese Remainder Theorem (CRT). The theorem states that if we have a system of congruences with pairwise coprime moduli, then there exists a unique solution modulo the product of the moduli. The given conditions can be written as a system of congruences: 1. x ≡ 5 (mod 8) 2. x ≡ 1 (mod 3) 3. x ≡ 7 (mod 11) We first need to check if the moduli (8, 3, and 11) are pairwise coprime, which means that no two of them have a common factor other than 1. Since 8, 3, and 11 are all prime numbers, they are indeed pairwise coprime. Now, we can apply the CRT to find the solution. The product of the moduli is 8 * 3 * 11 = 264. We need to find the solution modulo 264. To do this, we need to find the inverse of each modulus with respect to the other moduli and multiply them with the corresponding remainders. We then add these products together and take the result modulo 264. Let's find the inverses: - The inverse of 8 modulo 3 is 1 because 8 * 1 ≡ 1 (mod 3). - The inverse of 8 modulo 11 is 8 because 8 * 8 ≡ 1 (mod 11). - The inverse of 3 modulo 8 is 3 because 3 * 3 ≡ 1 (mod 8). - The inverse of 3 modulo 11 is 4 because 3 * 4 ≡ 1 (mod 11). - The inverse of 11 modulo 8 is 11 because 11 * 11 ≡ 1 (mod 8). - The inverse of 11 modulo 3 is 2 because 11 * 2 ≡ 1 (mod 3). Now, we multiply the inverses with the corresponding remainders and add them up: (8^-1 mod 3) * 5 * 3 + (8^-1 mod 11) * 5 * 11 + (3^-1 mod 8) * 1 * 8 + (3^-1 mod 11) * 1 * 11 + (11^-1 mod 8) * 7 * 8 + (11^-1 mod 3) * 7 * 3 = 1 * 5 * 3 + 8 * 5 * 11 + 3 * 1 * 8 + 4 * 1 * 11 + 11 * 7 * 8 + 2 * 7 * 3 = 15 + 440 + 24 + 44 + 616 + 42 = 1181 Now, we take the result modulo 264: 1181 mod 264 = 163 Therefore, the smallest positive integer that satisfies the given conditions is 163.	205
doubao	We can use the Chinese Remainder Theorem to solve this problem. For the first condition (remainder of 5 when divided by 8), we can write the number as 8a + 5. For the second condition (remainder of 1 when divided by 3), we can write the number as 3b + 1. For the third condition (remainder of 7 when divided by 11), we can write the number as 11c + 7. We want to find the same number that satisfies all these conditions. By trying different values of a, b, and c, we can find the smallest positive integer that works. Starting with a = 1, we get 8(1) + 5 = 13, but this doesn't satisfy the other conditions. Trying a = 2, we get 8(2) + 5 = 21, which doesn't work either. Continuing this process, we find that when a = 5, we get 8(5) + 5 = 45. Checking for the other conditions: 45 % 3 = 0 (not 1), so this doesn't work. When a = 6, we get 8(6) + 5 = 53. Checking: 53 % 3 = 1 (satisfies), 53 % 11 = 9 (not 7), so this doesn't work. When a = 7, we get 8(7) + 5 = 61. Checking: 61 % 3 = 1 (satisfies), 61 % 11 = 6 (not 7), so this doesn't work. When a = 8, we get 8(8) + 5 = 69. Checking: 69 % 3 = 0 (not 1), so this doesn't work. When a = 9, we get 8(9) + 5 = 77. Checking: 77 % 3 = 2 (not 1), so this doesn't work. When a = 10, we get 8(10) + 5 = 85. Checking: 85 % 3 = 1 (satisfies), 85 % 11 = 8 (not 7), so this doesn't work. When a = 11, we get 8(11) + 5 = 93. Checking: 93 % 3 = 0 (not 1), so this doesn't work. When a = 12, we get 8(12) + 5 = 101. Checking: 101 % 3 = 2 (not 1), so this doesn't work. When a = 13, we get 8(13) + 5 = 109. Checking: 109 % 3 = 1 (satisfies), 109 % 11 = 0 (not 7), so this doesn't work. When a = 14, we get 8(14) + 5 = 117. Checking: 117 % 3 = 0 (not 1), so this doesn't work. When a = 15, we get 8(15) + 5 = 125. Checking: 125 % 3 = 1 (satisfies), 125 % 11 = 4 (not 7), so this doesn't work. When a = 16, we get 8(16) + 5 = 133. Checking: 133 % 3 = 1 (satisfies), 133 % 11 = 10 (not 7), so this doesn't work. When a = 17, we get 8(17) + 5 = 141. Checking: 141 % 3 = 0 (not 1), so this doesn't work. When a = 18, we get 8(18) + 5 = 149. Checking: 149 % 3 = 1 (satisfies), 149 % 11 = 7 (satisfies)! So the smallest positive integer that satisfies all the conditions is 149.	205
minimax	To solve this problem, we can use the Chinese Remainder Theorem (CRT), which provides a way to solve systems of simultaneous congruences with pairwise coprime moduli. However, since the moduli are not pairwise coprime in this case (8 and 11 are not coprime), we need to find a solution that satisfies all the given conditions. Let's denote the smallest positive integer we are looking for as \( N \). The conditions given are: 1. \( N \equiv 5 \mod 8 \) 2. \( N \equiv 1 \mod 3 \) 3. \( N \equiv 7 \mod 11 \) We can start by listing a few numbers that satisfy each condition and then look for a common number that satisfies all three conditions. For the first condition, \( N \equiv 5 \mod 8 \), the numbers that satisfy this are: 5, 13, 21, 29, 37, 45, 53, 61, 69, 77, 85, 93, ... For the second condition, \( N \equiv 1 \mod 3 \), the numbers that satisfy this are: 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34, ... For the third condition, \( N \equiv 7 \mod 11 \), the numbers that satisfy this are: 7, 18, 29, 40, 51, 62, 73, 84, 95, 106, 117, ... Now, we look for a number that appears in all three lists. By inspection, we can see that the number 29 appears in the first and third lists, but not in the second. We need to find a number that appears in all three lists. Continuing this process, we find that the number 53 appears in the first list, but not in the second or third. We need to find a common number that satisfies all three conditions. If we continue this process, we will eventually find that the number 1001 does not satisfy any of the conditions, but 1001 + 1 = 1002 does satisfy the second condition. We can then add multiples of 8 * 3 * 11 = 264 (since 8, 3, and 11 are the least common multiples of the moduli in each condition) to 1002 until we find a number that satisfies all three conditions. By adding 264 repeatedly to 1002, we can check each new number to see if it satisfies all three conditions. This process can be tedious by hand, but we can use a simple program or algorithm to find the smallest such number. Here's a simple Python code snippet that can find the solution: ```python N = 1002 while True: if N % 8 == 5 and N % 3 == 1 and N % 11 == 7: break N += 264 print(N) ``` Running this code will give us the smallest positive integer \( N \) that satisfies all the given conditions. The output will be the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11.	205
kimi	To solve this problem, we can use the Chinese Remainder Theorem (CRT), which provides a way to find a number that satisfies a system of simultaneous congruences with different moduli. Given the system of congruences: \[ x \equiv 5 \pmod{8} \] \[ x \equiv 1 \pmod{3} \] \[ x \equiv 7 \pmod{11} \] We can denote these congruences as: \[ x = 8k + 5 \] for some integer \( k \) \[ x = 3m + 1 \] for some integer \( m \) \[ x = 11n + 7 \] for some integer \( n \] We want to find the smallest positive integer \( x \) that satisfies all three congruences. Let's start by finding a number that satisfies the first two congruences: \[ x = 8k + 5 \] \[ x = 3m + 1 \] We can express \( k \) in terms of \( x \) and substitute it into the second congruence: \[ 8k = x - 5 \] \[ k = \frac{x - 5}{8} \] Substitute \( k \) into the second congruence: \[ x = 3m + 1 \] \[ 3m = x - 1 \] \[ m = \frac{x - 1}{3} \] Now we need \( x \) to be an integer, so \( x - 1 \) must be divisible by 3. Let's find the smallest \( x \) such that \( x - 5 \) is divisible by 8 and \( x - 1 \) is divisible by 3. We can start by listing multiples of 8 and adding 5 to find the smallest number that is 1 more than a multiple of 3: \[ 8 \times 1 + 5 = 13 \] (not 1 more than a multiple of 3) \[ 8 \times 2 + 5 = 21 \] (not 1 more than a multiple of 3) \[ 8 \times 3 + 5 = 29 \] (not 1 more than a multiple of 3) \[ 8 \times 4 + 5 = 37 \] (not 1 more than a multiple of 3) \[ 8 \times 5 + 5 = 45 \] (not 1 more than a multiple of 3) \[ 8 \times 6 + 5 = 53 \] (not 1 more than a multiple of 3) \[ 8 \times 7 + 5 = 61 \] (not 1 more than a multiple of 3) \[ 8 \times 8 + 5 = 69 \] (not 1 more than a multiple of 3) \[ 8 \times 9 + 5 = 77 \] (not 1 more than a multiple of 3) \[ 8 \times 10 + 5 = 85 \] (not 1 more than a multiple of 3) \[ 8 \times 11 + 5 = 93 \] (not 1 more than a multiple of 3) \[ 8 \times 12 + 5 = 101 \] (101 is 1 more than a multiple of 3) So, \( x = 101 \) satisfies the first two congruences. Now we need to check if it satisfies the third congruence: \[ 101 \equiv 7 \pmod{11} \] Let's verify: \[ 101 - 7 = 94 \] \[ 94 \div 11 = 8 \text{ remainder } 6 \] Since 94 is not divisible by 11, 101 does not satisfy the third congruence. We need to find the next number that satisfies the first two congruences and then check against the third. We can continue this process, but it's more efficient to use a systematic approach. Let's find the least common multiple (LCM) of the moduli (8, 3, and 11) and then find the smallest number that satisfies the third congruence. The LCM of 8, 3, and 11 is 264 (since 8, 3, and 11 are pairwise coprime, the LCM is simply their product). Now we need to find the smallest \( x \) such that: \[ x \equiv 5 \pmod{8} \] \[ x \equiv 1 \	205
wenxinyiyan	To find the smallest positive integer that satisfies the given conditions, we can use the Chinese Remainder Theorem (CRT). The CRT states that if we have a system of congruences with coprime moduli, then there exists a unique solution modulo the product of the moduli. In this case, our system of congruences is: 1. x ≡ 5 (mod 8) 2. x ≡ 1 (mod 3) 3. x ≡ 7 (mod 11) The moduli 8, 3, and 11 are coprime, so we can apply the CRT. First, we find the product of the moduli: 8 * 3 * 11 = 264 Next, we compute the partial products: M1 = 264 / 8 = 33 M2 = 264 / 3 = 88 M3 = 264 / 11 = 24 Now, we find the modular inverses of the partial products with respect to the corresponding moduli: 1. 33^-1 ≡ 3 (mod 8) because 33 * 3 ≡ 1 (mod 8) 2. 88^-1 ≡ 1 (mod 3) because 88 * 1 ≡ 1 (mod 3) 3. 24^-1 ≡ 2 (mod 11) because 24 * 2 ≡ 1 (mod 11) Finally, we compute the solution x using the CRT formula: x ≡ (5 * 33 * 3) + (1 * 88 * 1) + (7 * 24 * 2) (mod 264) x ≡ (495 + 88 + 336) (mod 264) x ≡ 919 (mod 264) Since we are looking for the smallest positive integer, we can reduce x modulo 264: x ≡ 919 - 3 * 264 x ≡ 127 Therefore, the smallest positive integer that satisfies the given conditions is 127.	205
zhipu	To solve this problem, we can use the Chinese Remainder Theorem (CRT), which provides a solution to the problem of finding an integer that has a specified set of remainders when divided by several pairwise coprime integers. The problem can be translated into the following system of congruences: 1. \( x \equiv 5 \mod 8 \) 2. \( x \equiv 1 \mod 3 \) 3. \( x \equiv 7 \mod 11 \) Since 8, 3, and 11 are pairwise coprime (no two of them share a common divisor other than 1), the Chinese Remainder Theorem guarantees that there exists a unique solution modulo the product of these numbers, which is \( 8 \times 3 \times 11 = 264 \). Now, let's solve the system step by step. Step 1: Solve the first two congruences: Let's find an integer \( x \) such that: \( x \equiv 5 \mod 8 \) \( x \equiv 1 \mod 3 \) We can write \( x \) as \( x = 8k + 5 \) for some integer \( k \), and substitute this into the second congruence: \( 8k + 5 \equiv 1 \mod 3 \) Since \( 8 \equiv 2 \mod 3 \), we have: \( 2k + 5 \equiv 1 \mod 3 \) \( 2k \equiv -4 \mod 3 \) \( 2k \equiv 2 \mod 3 \) (because \(-4 \equiv 2 \mod 3\)) Now we need to find the multiplicative inverse of 2 modulo 3, which is 2, because \( 2 \times 2 \equiv 1 \mod 3 \). Multiplying both sides by 2, we get: \( k \equiv 1 \mod 3 \) So we can write \( k \) as \( k = 3m + 1 \) for some integer \( m \). Substituting back into \( x = 8k + 5 \), we get: \( x = 8(3m + 1) + 5 \) \( x = 24m + 8 + 5 \) \( x = 24m + 13 \) So \( x \equiv 13 \mod 24 \) satisfies both the first and second congruences. Step 2: Combine this result with the third congruence: Now we have: \( x \equiv 13 \mod 24 \) \( x \equiv 7 \mod 11 \) We can write \( x \) as \( x = 24n + 13 \) for some integer \( n \), and substitute this into the third congruence: \( 24n + 13 \equiv 7 \mod 11 \) Since \( 24 \equiv 2 \mod 11 \), we have: \( 2n + 13 \equiv 7 \mod 11 \) \( 2n \equiv -6 \mod 11 \) \( 2n \equiv 5 \mod 11 \) (because \(-6 \equiv 5 \mod 11\)) Now we need to find the multiplicative inverse of 2 modulo 11, which is 6, because \( 2 \times 6 \equiv 1 \mod 11 \). Multiplying both sides by 6, we get: \( n \equiv 30 \mod 11 \) \( n \equiv 8 \mod 11 \) (because \( 30 \equiv 8 \mod 11 \)) So we can write \( n \) as \( n = 11p + 8 \) for some integer \( p \). Substituting back into \( x = 24n + 13 \), we get: \( x = 24(11p + 8) + 13 \) \( x = 264p + 192 + 13 \) \( x = 264p + 205 \) The smallest positive integer solution is when \( p = 0 \), which gives us \( x = 205 \). Therefore, the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11 is \( \boxed{205} \).	205
gpto1	To solve the problem, we need to find the smallest positive integer \( N \) that satisfies the following three congruences: 1. \( N \equiv 5 \mod 8 \) 2. \( N \equiv 1 \mod 3 \) 3. \( N \equiv 7 \mod 11 \) We will use the Chinese Remainder Theorem (CRT) to find a solution that satisfies all three congruences simultaneously. Step 1: Solve the first two congruences First, consider the congruences: - \( N \equiv 5 \mod 8 \) - \( N \equiv 1 \mod 3 \) Let’s express \( N \) in terms of \( k \): \[ N = 8k + 5 \] Now substitute \( N \) into the second congruence: \[ 8k + 5 \equiv 1 \mod 3 \] Simplify by computing modulo 3: - \( 8 \mod 3 = 2 \) - \( 5 \mod 3 = 2 \) So the equation becomes: \[ 2k + 2 \equiv 1 \mod 3 \] Subtract 2 from both sides: \[ 2k \equiv -1 \mod 3 \] Since \( -1 \mod 3 = 2 \), the equation simplifies to: \[ 2k \equiv 2 \mod 3 \] To solve for \( k \), multiply both sides by the modular inverse of 2 modulo 3. The modular inverse of 2 modulo 3 is 2 because \( 2 \times 2 \equiv 1 \mod 3 \). \[ k \equiv 2 \times 2 \mod 3 \] \[ k \equiv 4 \mod 3 \] \[ k \equiv 1 \mod 3 \] So \( k = 3m + 1 \), where \( m \) is an integer. Substitute back into the expression for \( N \): \[ N = 8(3m + 1) + 5 \] \[ N = 24m + 8 + 5 \] \[ N = 24m + 13 \] This means: \[ N \equiv 13 \mod 24 \] Step 2: Combine with the third congruence Now consider the congruences: - \( N \equiv 13 \mod 24 \) - \( N \equiv 7 \mod 11 \) Express \( N \) in terms of a new variable \( p \): \[ N = 24p + 13 \] Substitute \( N \) into the third congruence: \[ 24p + 13 \equiv 7 \mod 11 \] Simplify by computing modulo 11: - \( 24 \mod 11 = 2 \) - \( 13 \mod 11 = 2 \) So the equation becomes: \[ 2p + 2 \equiv 7 \mod 11 \] Subtract 2 from both sides: \[ 2p \equiv 5 \mod 11 \] To solve for \( p \), multiply both sides by the modular inverse of 2 modulo 11. The modular inverse of 2 modulo 11 is 6 because \( 2 \times 6 \equiv 1 \mod 11 \). \[ p \equiv 6 \times 5 \mod 11 \] \[ p \equiv 30 \mod 11 \] \[ p \equiv 8 \mod 11 \] So \( p = 11n + 8 \), where \( n \) is an integer. Substitute back into the expression for \( N \): \[ N = 24(11n + 8) + 13 \] \[ N = 264n + 192 + 13 \] \[ N = 264n + 205 \] Step 3: Find the smallest positive integer \( N \) Since \( n \) is an integer and we seek the smallest positive \( N \), set \( n = 0 \): \[ N = 264 \times 0 + 205 \] \[ N = 205 \] Answer: \[ \boxed{205} \]	205

To solve this problem, we need to find a number that satisfies the following conditions:

1. The number leaves a remainder of 5 when divided by 8.
2. The number leaves a remainder of 1 when divided by 3.
3. The number leaves a remainder of 7 when divided by 11.

This can be represented by the following system of congruences:

x ≡ 5 (mod 8)
x ≡ 1 (mod 3)
x ≡ 7 (mod 11)

To solve this system, we can use the Chinese Remainder Theorem (CRT). The CRT states that if the moduli are pairwise coprime (which they are in this case: 8, 3, and 11), there exists a unique solution modulo the product of the moduli.

Let's denote:
M = 8 * 3 * 11 = 264

Now, we need to find the partial products:
M1 = M / 8 = 264 / 8 = 33
M2 = M / 3 = 264 / 3 = 88
M3 = M / 11 = 264 / 11 = 24

Next, we need to find the modular inverses:
y1 = M1^(-1) mod 8
y2 = M2^(-1) mod 3
y3 = M3^(-1) mod 11

We can calculate these inverses as follows:
y1 = 33^(-1) mod 8 = 5
y2 = 88^(-1) mod 3 = 2
y3 = 24^(-1) mod 11 = 2

Now we can calculate x using the following formula:
x = (5 * 33 * 5) + (1 * 88 * 2) + (7 * 24 * 2) mod 264
x = (825) + (176) + (336) mod 264
x = 1337 mod 264
x = 241

Therefore, the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11 is 241.

To find the smallest positive integer \( N \) that satisfies the following congruences:
1. \( N \equiv 5 \pmod{8} \)
2. \( N \equiv 1 \pmod{3} \)
3. \( N \equiv 7 \pmod{11} \)

We start by solving the first two congruences. Express \( N \) as \( N = 8k + 5 \). Substituting this into the second congruence:
\[
8k + 5 \equiv 1 \pmod{3}
\]
Simplifying, we get:
\[
8k + 5 \equiv 1 \pmod{3} \implies 2k + 2 \equiv 1 \pmod{3} \implies 2k \equiv -1 \pmod{3} \implies 2k \equiv 2 \pmod{3} \implies k \equiv 1 \pmod{3}
\]
Thus, \( k = 3m + 1 \) for some integer \( m \). Substituting back, we get:
\[
N = 8(3m + 1) + 5 = 24m + 13
\]
So, \( N \equiv 13 \pmod{24} \).

Next, we incorporate the third congruence. Express \( N \) as \( N = 24m + 13 \). Substituting this into the third congruence:
\[
24m + 13 \equiv 7 \pmod{11}
\]
Simplifying, we get:
\[
24m + 13 \equiv 7 \pmod{11} \implies 2m + 2 \equiv 7 \pmod{11} \implies 2m \equiv 5 \pmod{11}
\]
The multiplicative inverse of 2 modulo 11 is 6, so:
\[
m \equiv 5 \cdot 6 \pmod{11} \implies m \equiv 30 \pmod{11} \implies m \equiv 8 \pmod{11}
\]
Thus, \( m = 11n + 8 \) for some integer \( n \). Substituting back, we get:
\[
N = 24(11n + 8) + 13 = 264n + 205
\]
Therefore, the smallest positive integer solution is \( N = 205 \) when \( n = 0 \).

Verification:
1. \( 205 \div 8 = 25 \) remainder \( 5 \)
2. \( 205 \div 3 = 68 \) remainder \( 1 \)
3. \( 205 \div 11 = 18 \) remainder \( 7 \)

All conditions are satisfied. The smallest positive integer is \(\boxed{205}\).

To solve the problem, we need to find the smallest positive integer \( N \) that satisfies the following three congruences:

1. \( N \equiv 5 \mod 8 \)
2. \( N \equiv 1 \mod 3 \)
3. \( N \equiv 7 \mod 11 \)

We will use the **Chinese Remainder Theorem (CRT)** to find a solution that satisfies all three congruences simultaneously.

**Step 1: Solve the first two congruences**

First, consider the congruences:

- \( N \equiv 5 \mod 8 \)
- \( N \equiv 1 \mod 3 \)

Let’s express \( N \) in terms of \( k \):

\[ N = 8k + 5 \]

Now substitute \( N \) into the second congruence:

\[ 8k + 5 \equiv 1 \mod 3 \]

Simplify by computing modulo 3:

- \( 8 \mod 3 = 2 \)
- \( 5 \mod 3 = 2 \)

So the equation becomes:

\[ 2k + 2 \equiv 1 \mod 3 \]

Subtract 2 from both sides:

\[ 2k \equiv -1 \mod 3 \]

Since \( -1 \mod 3 = 2 \), the equation simplifies to:

\[ 2k \equiv 2 \mod 3 \]

To solve for \( k \), multiply both sides by the modular inverse of 2 modulo 3. The modular inverse of 2 modulo 3 is 2 because \( 2 \times 2 \equiv 1 \mod 3 \).

\[ k \equiv 2 \times 2 \mod 3 \]
\[ k \equiv 4 \mod 3 \]
\[ k \equiv 1 \mod 3 \]

So \( k = 3m + 1 \), where \( m \) is an integer.

Substitute back into the expression for \( N \):

\[ N = 8(3m + 1) + 5 \]
\[ N = 24m + 8 + 5 \]
\[ N = 24m + 13 \]

This means:

\[ N \equiv 13 \mod 24 \]

**Step 2: Combine with the third congruence**

Now consider the congruences:

- \( N \equiv 13 \mod 24 \)
- \( N \equiv 7 \mod 11 \)

Express \( N \) in terms of a new variable \( p \):

\[ N = 24p + 13 \]

Substitute \( N \) into the third congruence:

\[ 24p + 13 \equiv 7 \mod 11 \]

Simplify by computing modulo 11:

- \( 24 \mod 11 = 2 \)
- \( 13 \mod 11 = 2 \)

So the equation becomes:

\[ 2p + 2 \equiv 7 \mod 11 \]

Subtract 2 from both sides:

\[ 2p \equiv 5 \mod 11 \]

To solve for \( p \), multiply both sides by the modular inverse of 2 modulo 11. The modular inverse of 2 modulo 11 is 6 because \( 2 \times 6 \equiv 1 \mod 11 \).

\[ p \equiv 6 \times 5 \mod 11 \]
\[ p \equiv 30 \mod 11 \]
\[ p \equiv 8 \mod 11 \]

So \( p = 11n + 8 \), where \( n \) is an integer.

Substitute back into the expression for \( N \):

\[ N = 24(11n + 8) + 13 \]
\[ N = 264n + 192 + 13 \]
\[ N = 264n + 205 \]

**Step 3: Find the smallest positive integer \( N \)**

Since \( n \) is an integer and we seek the smallest positive \( N \), set \( n = 0 \):

\[ N = 264 \times 0 + 205 \]
\[ N = 205 \]

**Answer:**

\[ \boxed{205} \]

GPT-4o

To solve the problem, we need to find the smallest positive integer \( x \) that satisfies the following system of congruences:

1. \( x \equiv 5 \pmod{8} \)
2. \( x \equiv 1 \pmod{3} \)
3. \( x \equiv 7 \pmod{11} \)

We will solve this step by step using the method of successive substitutions, also known as the Chinese Remainder Theorem in an informal way.

1. Start with the first congruence:
\[ x \equiv 5 \pmod{8} \]
This means \( x = 8k + 5 \) for some integer \( k \).

2. Substitute \( x = 8k + 5 \) into the second congruence:
\[ 8k + 5 \equiv 1 \pmod{3} \]
Simplify the congruence:
\[ 8k + 5 \equiv 1 \pmod{3} \]
Since \( 8 \equiv 2 \pmod{3} \) and \( 5 \equiv 2 \pmod{3} \):
\[ 2k + 2 \equiv 1 \pmod{3} \]
\[ 2k \equiv -1 \pmod{3} \]
\[ 2k \equiv 2 \pmod{3} \]
\[ k \equiv 1 \pmod{3} \]
Therefore, \( k = 3m + 1 \) for some integer \( m \).

3. Substitute \( k = 3m + 1 \) back into \( x = 8k + 5 \):
\[ x = 8(3m + 1) + 5 \]
\[ x = 24m + 8 + 5 \]
\[ x = 24m + 13 \]
So, \( x \equiv 13 \pmod{24} \).

4. Substitute \( x = 24m + 13 \) into the third congruence:
\[ 24m + 13 \equiv 7 \pmod{11} \]
Simplify the congruence:
\[ 24m + 13 \equiv 7 \pmod{11} \]
Since \( 24 \equiv 2 \pmod{11} \) and \( 13 \equiv 2 \pmod{11} \):
\[ 2m + 2 \equiv 7 \pmod{11} \]
\[ 2m \equiv 5 \pmod{11} \]
To solve for \( m \), we need the multiplicative inverse of 2 modulo 11, which is 6 (since \( 2 \times 6 = 12 \equiv 1 \pmod{11} \)):
\[ m \equiv 5 \times 6 \pmod{11} \]
\[ m \equiv 30 \pmod{11} \]
\[ m \equiv 8 \pmod{11} \]
Therefore, \( m = 11n + 8 \) for some integer \( n \).

5. Substitute \( m = 11n + 8 \) back into \( x = 24m + 13 \):
\[ x = 24(11n + 8) + 13 \]
\[ x = 264n + 192 + 13 \]
\[ x = 264n + 205 \]

The smallest positive \( x \) occurs when \( n = 0 \):
\[ x = 205 \]

Therefore, the smallest positive integer that satisfies all the given congruences is \( \boxed{205} \).

To find the smallest positive integer that satisfies the given conditions, we can use the Chinese Remainder Theorem (CRT). The CRT states that if we have a system of congruences:

x ≡ a1 (mod n1)
x ≡ a2 (mod n2)
...
x ≡ ak (mod nk)

where ni are pairwise coprime (i.e., gcd(ni, nj) = 1 for i ≠ j), then there exists a unique solution modulo N = n1n2...nk.

In this case, we have:

x ≡ 5 (mod 8)
x ≡ 1 (mod 3)
x ≡ 7 (mod 11)

First, we need to find the least common multiple (LCM) of 8, 3, and 11, which is 264.

Next, we can use the CRT to find the solution. We can start by finding the solution modulo 8:

x ≡ 5 (mod 8)

This means x = 5 + 8k for some integer k.

Now, we need to find the solution modulo 3:

x ≡ 1 (mod 3)

Substituting x = 5 + 8k, we get:

5 + 8k ≡ 1 (mod 3)

Simplifying, we get:

2k ≡ -4 (mod 3)

k ≡ 2 (mod 3)

So, k = 2 + 3m for some integer m.

Now, we substitute k = 2 + 3m into x = 5 + 8k:

x = 5 + 8(2 + 3m)
= 5 + 16 + 24m
= 21 + 24m

Finally, we need to find the solution modulo 11:

x ≡ 7 (mod 11)

Substituting x = 21 + 24m, we get:

21 + 24m ≡ 7 (mod 11)

Simplifying, we get:

10m ≡ -14 (mod 11)

m ≡ 4 (mod 11)

So, m = 4 + 11n for some integer n.

Substituting m = 4 + 11n into x = 21 + 24m, we get:

x = 21 + 24(4 + 11n)
= 21 + 96 + 264n
= 117 + 264n

Therefore, the smallest positive integer that satisfies the given conditions is x = 117.

To find the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11, we can use the Chinese Remainder Theorem (CRT).

First, we need to find the least common multiple (LCM) of 8, 3, and 11, which is 264.

Next, we need to find the solutions to the following congruences:

x ≡ 5 (mod 8)
x ≡ 1 (mod 3)
x ≡ 7 (mod 11)

Using the CRT, we can find the solution to the first congruence:

x ≡ 5 (mod 8)
x = 5 + 8k

where k is an integer.

Substituting this solution into the second congruence, we get:

5 + 8k ≡ 1 (mod 3)
8k ≡ -4 (mod 3)
k ≡ 2 (mod 3)

So, k = 2 + 3m, where m is an integer.

Substituting this value of k into the solution to the first congruence, we get:

x = 5 + 8(2 + 3m)
x = 21 + 24m

Now, we need to find the solution to the third congruence:

x ≡ 7 (mod 11)
21 + 24m ≡ 7 (mod 11)
24m ≡ -14 (mod 11)
m ≡ 3 (mod 11)

So, m = 3 + 11n, where n is an integer.

Substituting this value of m into the solution to the second congruence, we get:

x = 21 + 24(3 + 11n)
x = 93 + 264n

Therefore, the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11 is 93.

x \equiv 7 \pmod{11}

We will use the method of successive substitutions to find the solution.

### Step 1: Solve the first two congruences

First, consider the congruences:
\[
\begin{cases}
x \equiv 5 \pmod{8} \\
x \equiv 1 \pmod{3}
\end{cases}
\]

We can express \( x \) in terms of the first congruence:
\[
x = 8k + 5 \quad \text{for some integer } k
\]

Substitute \( x = 8k + 5 \) into the second congruence:
\[
8k + 5 \equiv 1 \pmod{3}
\]

Simplify the congruence:
\[
8k + 5 \equiv 1 \pmod{3} \implies 2k + 2 \equiv 1 \pmod{3} \implies 2k \equiv -1 \pmod{3} \implies 2k \equiv 2 \pmod{3}
\]

Since \( 2 \) and \( 3 \) are coprime, we can divide both sides by \( 2 \):
\[
k \equiv 1 \pmod{3}
\]

Thus, \( k \) can be written as:
\[
k = 3m + 1 \quad \text{for some integer } m
\]

Substitute \( k = 3m + 1 \) back into \( x = 8k + 5 \):
\[
x = 8(3m + 1) + 5 = 24m + 8 + 5 = 24m + 13
\]

So, we have:
\[
x \equiv 13 \pmod{24}
\]

### Step 2: Solve the combined congruence with the third congruence

Now, consider the combined congruence with the third congruence:
\[
\begin{cases}
x \equiv 13 \pmod{24} \\
x \equiv 7 \pmod{11}
\end{cases}
\]

We can express \( x \) in terms of the first combined congruence:
\[
x = 24n + 13 \quad \text{for some integer } n
\]

Substitute \( x = 24n + 13 \) into the third congruence:
\[
24n + 13 \equiv 7 \pmod{11}
\]

Simplify the congruence:
\[
24n + 13 \equiv 7 \pmod{11} \implies 2n + 2 \equiv 7 \pmod{11} \implies 2n \equiv 5 \pmod{11}
\]

To solve \( 2n \equiv 5 \pmod{11} \), we need the multiplicative inverse of \( 2 \) modulo \( 11 \). The inverse of \( 2 \) modulo \( 11 \) is \( 6 \) because:
\[
2 \cdot 6 \equiv 1 \pmod{11}
\]

Multiply both sides of \( 2n \equiv 5 \pmod{11} \) by \( 6 \):
\[
n \equiv 30 \pmod{11} \implies n \equiv 8 \pmod{11}
\]

Thus, \( n \) can be written as:
\[
n = 11p + 8 \quad \text{for some integer } p
\]

Substitute \( n = 11p + 8 \) back into \( x = 24n + 13 \):
\[
x = 24(11p + 8) + 13 = 264p + 192 + 13 = 264p + 205
\]

So, the smallest positive integer \( x \) is:
\[
x = 205
\]

Thus, the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11 is:

\[
\boxed{205}
\]

To find the smallest positive integer that satisfies the given conditions, we can use the Chinese Remainder Theorem (CRT). The theorem states that if we have a system of congruences with pairwise coprime moduli, then there exists a unique solution modulo the product of the moduli.

The given conditions can be written as a system of congruences:

1. x ≡ 5 (mod 8)
2. x ≡ 1 (mod 3)
3. x ≡ 7 (mod 11)

We first need to check if the moduli (8, 3, and 11) are pairwise coprime, which means that no two of them have a common factor other than 1. Since 8, 3, and 11 are all prime numbers, they are indeed pairwise coprime.

Now, we can apply the CRT to find the solution. The product of the moduli is 8 * 3 * 11 = 264. We need to find the solution modulo 264.

To do this, we need to find the inverse of each modulus with respect to the other moduli and multiply them with the corresponding remainders. We then add these products together and take the result modulo 264.

Let's find the inverses:

- The inverse of 8 modulo 3 is 1 because 8 * 1 ≡ 1 (mod 3).
- The inverse of 8 modulo 11 is 8 because 8 * 8 ≡ 1 (mod 11).
- The inverse of 3 modulo 8 is 3 because 3 * 3 ≡ 1 (mod 8).
- The inverse of 3 modulo 11 is 4 because 3 * 4 ≡ 1 (mod 11).
- The inverse of 11 modulo 8 is 11 because 11 * 11 ≡ 1 (mod 8).
- The inverse of 11 modulo 3 is 2 because 11 * 2 ≡ 1 (mod 3).

Now, we multiply the inverses with the corresponding remainders and add them up:

(8^-1 mod 3) * 5 * 3 + (8^-1 mod 11) * 5 * 11 + (3^-1 mod 8) * 1 * 8 + (3^-1 mod 11) * 1 * 11 + (11^-1 mod 8) * 7 * 8 + (11^-1 mod 3) * 7 * 3
= 1 * 5 * 3 + 8 * 5 * 11 + 3 * 1 * 8 + 4 * 1 * 11 + 11 * 7 * 8 + 2 * 7 * 3
= 15 + 440 + 24 + 44 + 616 + 42
= 1181

Now, we take the result modulo 264:

1181 mod 264 = 163

Therefore, the smallest positive integer that satisfies the given conditions is 163.

We can use the Chinese Remainder Theorem to solve this problem.

For the first condition (remainder of 5 when divided by 8), we can write the number as 8a + 5.

For the second condition (remainder of 1 when divided by 3), we can write the number as 3b + 1.

For the third condition (remainder of 7 when divided by 11), we can write the number as 11c + 7.

We want to find the same number that satisfies all these conditions.

By trying different values of a, b, and c, we can find the smallest positive integer that works.

Starting with a = 1, we get 8(1) + 5 = 13, but this doesn't satisfy the other conditions.

Trying a = 2, we get 8(2) + 5 = 21, which doesn't work either.

Continuing this process, we find that when a = 5, we get 8(5) + 5 = 45.

Checking for the other conditions: 45 % 3 = 0 (not 1), so this doesn't work.

When a = 6, we get 8(6) + 5 = 53.

Checking: 53 % 3 = 1 (satisfies), 53 % 11 = 9 (not 7), so this doesn't work.

When a = 7, we get 8(7) + 5 = 61.

Checking: 61 % 3 = 1 (satisfies), 61 % 11 = 6 (not 7), so this doesn't work.

When a = 8, we get 8(8) + 5 = 69.

Checking: 69 % 3 = 0 (not 1), so this doesn't work.

When a = 9, we get 8(9) + 5 = 77.

Checking: 77 % 3 = 2 (not 1), so this doesn't work.

When a = 10, we get 8(10) + 5 = 85.

Checking: 85 % 3 = 1 (satisfies), 85 % 11 = 8 (not 7), so this doesn't work.

When a = 11, we get 8(11) + 5 = 93.

Checking: 93 % 3 = 0 (not 1), so this doesn't work.

When a = 12, we get 8(12) + 5 = 101.

Checking: 101 % 3 = 2 (not 1), so this doesn't work.

When a = 13, we get 8(13) + 5 = 109.

Checking: 109 % 3 = 1 (satisfies), 109 % 11 = 0 (not 7), so this doesn't work.

When a = 14, we get 8(14) + 5 = 117.

Checking: 117 % 3 = 0 (not 1), so this doesn't work.

When a = 15, we get 8(15) + 5 = 125.

Checking: 125 % 3 = 1 (satisfies), 125 % 11 = 4 (not 7), so this doesn't work.

When a = 16, we get 8(16) + 5 = 133.

Checking: 133 % 3 = 1 (satisfies), 133 % 11 = 10 (not 7), so this doesn't work.

When a = 17, we get 8(17) + 5 = 141.

Checking: 141 % 3 = 0 (not 1), so this doesn't work.

When a = 18, we get 8(18) + 5 = 149.

Checking: 149 % 3 = 1 (satisfies), 149 % 11 = 7 (satisfies)!

So the smallest positive integer that satisfies all the conditions is 149.

To solve this problem, we can use the Chinese Remainder Theorem (CRT), which provides a way to solve systems of simultaneous congruences with pairwise coprime moduli. However, since the moduli are not pairwise coprime in this case (8 and 11 are not coprime), we need to find a solution that satisfies all the given conditions.

Let's denote the smallest positive integer we are looking for as \( N \).

The conditions given are:
1. \( N \equiv 5 \mod 8 \)
2. \( N \equiv 1 \mod 3 \)
3. \( N \equiv 7 \mod 11 \)

We can start by listing a few numbers that satisfy each condition and then look for a common number that satisfies all three conditions.

For the first condition, \( N \equiv 5 \mod 8 \), the numbers that satisfy this are:
5, 13, 21, 29, 37, 45, 53, 61, 69, 77, 85, 93, ...

For the second condition, \( N \equiv 1 \mod 3 \), the numbers that satisfy this are:
1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34, ...

For the third condition, \( N \equiv 7 \mod 11 \), the numbers that satisfy this are:
7, 18, 29, 40, 51, 62, 73, 84, 95, 106, 117, ...

Now, we look for a number that appears in all three lists. By inspection, we can see that the number 29 appears in the first and third lists, but not in the second. We need to find a number that appears in all three lists.

Continuing this process, we find that the number 53 appears in the first list, but not in the second or third. We need to find a common number that satisfies all three conditions.

If we continue this process, we will eventually find that the number 1001 does not satisfy any of the conditions, but 1001 + 1 = 1002 does satisfy the second condition. We can then add multiples of 8 * 3 * 11 = 264 (since 8, 3, and 11 are the least common multiples of the moduli in each condition) to 1002 until we find a number that satisfies all three conditions.

By adding 264 repeatedly to 1002, we can check each new number to see if it satisfies all three conditions. This process can be tedious by hand, but we can use a simple program or algorithm to find the smallest such number.

Here's a simple Python code snippet that can find the solution:

```python
N = 1002
while True:
if N % 8 == 5 and N % 3 == 1 and N % 11 == 7:
break
N += 264
print(N)
```

Running this code will give us the smallest positive integer \( N \) that satisfies all the given conditions. The output will be the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11.

To solve this problem, we can use the Chinese Remainder Theorem (CRT), which provides a way to find a number that satisfies a system of simultaneous congruences with different moduli.

Given the system of congruences:
\[ x \equiv 5 \pmod{8} \]
\[ x \equiv 1 \pmod{3} \]
\[ x \equiv 7 \pmod{11} \]

We can denote these congruences as:
\[ x = 8k + 5 \] for some integer \( k \)
\[ x = 3m + 1 \] for some integer \( m \)
\[ x = 11n + 7 \] for some integer \( n \]

We want to find the smallest positive integer \( x \) that satisfies all three congruences.

Let's start by finding a number that satisfies the first two congruences:
\[ x = 8k + 5 \]
\[ x = 3m + 1 \]

We can express \( k \) in terms of \( x \) and substitute it into the second congruence:
\[ 8k = x - 5 \]
\[ k = \frac{x - 5}{8} \]

Substitute \( k \) into the second congruence:
\[ x = 3m + 1 \]
\[ 3m = x - 1 \]
\[ m = \frac{x - 1}{3} \]

Now we need \( x \) to be an integer, so \( x - 1 \) must be divisible by 3. Let's find the smallest \( x \) such that \( x - 5 \) is divisible by 8 and \( x - 1 \) is divisible by 3.

We can start by listing multiples of 8 and adding 5 to find the smallest number that is 1 more than a multiple of 3:
\[ 8 \times 1 + 5 = 13 \] (not 1 more than a multiple of 3)
\[ 8 \times 2 + 5 = 21 \] (not 1 more than a multiple of 3)
\[ 8 \times 3 + 5 = 29 \] (not 1 more than a multiple of 3)
\[ 8 \times 4 + 5 = 37 \] (not 1 more than a multiple of 3)
\[ 8 \times 5 + 5 = 45 \] (not 1 more than a multiple of 3)
\[ 8 \times 6 + 5 = 53 \] (not 1 more than a multiple of 3)
\[ 8 \times 7 + 5 = 61 \] (not 1 more than a multiple of 3)
\[ 8 \times 8 + 5 = 69 \] (not 1 more than a multiple of 3)
\[ 8 \times 9 + 5 = 77 \] (not 1 more than a multiple of 3)
\[ 8 \times 10 + 5 = 85 \] (not 1 more than a multiple of 3)
\[ 8 \times 11 + 5 = 93 \] (not 1 more than a multiple of 3)
\[ 8 \times 12 + 5 = 101 \] (101 is 1 more than a multiple of 3)

So, \( x = 101 \) satisfies the first two congruences. Now we need to check if it satisfies the third congruence:
\[ 101 \equiv 7 \pmod{11} \]

Let's verify:
\[ 101 - 7 = 94 \]
\[ 94 \div 11 = 8 \text{ remainder } 6 \]

Since 94 is not divisible by 11, 101 does not satisfy the third congruence. We need to find the next number that satisfies the first two congruences and then check against the third.

We can continue this process, but it's more efficient to use a systematic approach. Let's find the least common multiple (LCM) of the moduli (8, 3, and 11) and then find the smallest number that satisfies the third congruence.

The LCM of 8, 3, and 11 is 264 (since 8, 3, and 11 are pairwise coprime, the LCM is simply their product).

Now we need to find the smallest \( x \) such that:
\[ x \equiv 5 \pmod{8} \]
\[ x \equiv 1 \

To find the smallest positive integer that satisfies the given conditions, we can use the Chinese Remainder Theorem (CRT). The CRT states that if we have a system of congruences with coprime moduli, then there exists a unique solution modulo the product of the moduli.

In this case, our system of congruences is:

1. x ≡ 5 (mod 8)
2. x ≡ 1 (mod 3)
3. x ≡ 7 (mod 11)

The moduli 8, 3, and 11 are coprime, so we can apply the CRT.

First, we find the product of the moduli:
8 * 3 * 11 = 264

Next, we compute the partial products:
M1 = 264 / 8 = 33
M2 = 264 / 3 = 88
M3 = 264 / 11 = 24

Now, we find the modular inverses of the partial products with respect to the corresponding moduli:

1. 33^-1 ≡ 3 (mod 8) because 33 * 3 ≡ 1 (mod 8)
2. 88^-1 ≡ 1 (mod 3) because 88 * 1 ≡ 1 (mod 3)
3. 24^-1 ≡ 2 (mod 11) because 24 * 2 ≡ 1 (mod 11)

Finally, we compute the solution x using the CRT formula:
x ≡ (5 * 33 * 3) + (1 * 88 * 1) + (7 * 24 * 2) (mod 264)
x ≡ (495 + 88 + 336) (mod 264)
x ≡ 919 (mod 264)

Since we are looking for the smallest positive integer, we can reduce x modulo 264:
x ≡ 919 - 3 * 264
x ≡ 127

Therefore, the smallest positive integer that satisfies the given conditions is 127.

To solve this problem, we can use the Chinese Remainder Theorem (CRT), which provides a solution to the problem of finding an integer that has a specified set of remainders when divided by several pairwise coprime integers.

The problem can be translated into the following system of congruences:

1. \( x \equiv 5 \mod 8 \)
2. \( x \equiv 1 \mod 3 \)
3. \( x \equiv 7 \mod 11 \)

Since 8, 3, and 11 are pairwise coprime (no two of them share a common divisor other than 1), the Chinese Remainder Theorem guarantees that there exists a unique solution modulo the product of these numbers, which is \( 8 \times 3 \times 11 = 264 \).

Now, let's solve the system step by step.

Step 1: Solve the first two congruences:

Let's find an integer \( x \) such that:
\( x \equiv 5 \mod 8 \)
\( x \equiv 1 \mod 3 \)

We can write \( x \) as \( x = 8k + 5 \) for some integer \( k \), and substitute this into the second congruence:
\( 8k + 5 \equiv 1 \mod 3 \)

Since \( 8 \equiv 2 \mod 3 \), we have:
\( 2k + 5 \equiv 1 \mod 3 \)
\( 2k \equiv -4 \mod 3 \)
\( 2k \equiv 2 \mod 3 \) (because \(-4 \equiv 2 \mod 3\))

Now we need to find the multiplicative inverse of 2 modulo 3, which is 2, because \( 2 \times 2 \equiv 1 \mod 3 \). Multiplying both sides by 2, we get:
\( k \equiv 1 \mod 3 \)

So we can write \( k \) as \( k = 3m + 1 \) for some integer \( m \). Substituting back into \( x = 8k + 5 \), we get:
\( x = 8(3m + 1) + 5 \)
\( x = 24m + 8 + 5 \)
\( x = 24m + 13 \)

So \( x \equiv 13 \mod 24 \) satisfies both the first and second congruences.

Step 2: Combine this result with the third congruence:

Now we have:
\( x \equiv 13 \mod 24 \)
\( x \equiv 7 \mod 11 \)

We can write \( x \) as \( x = 24n + 13 \) for some integer \( n \), and substitute this into the third congruence:
\( 24n + 13 \equiv 7 \mod 11 \)

Since \( 24 \equiv 2 \mod 11 \), we have:
\( 2n + 13 \equiv 7 \mod 11 \)
\( 2n \equiv -6 \mod 11 \)
\( 2n \equiv 5 \mod 11 \) (because \(-6 \equiv 5 \mod 11\))

Now we need to find the multiplicative inverse of 2 modulo 11, which is 6, because \( 2 \times 6 \equiv 1 \mod 11 \). Multiplying both sides by 6, we get:
\( n \equiv 30 \mod 11 \)
\( n \equiv 8 \mod 11 \) (because \( 30 \equiv 8 \mod 11 \))

So we can write \( n \) as \( n = 11p + 8 \) for some integer \( p \). Substituting back into \( x = 24n + 13 \), we get:
\( x = 24(11p + 8) + 13 \)
\( x = 264p + 192 + 13 \)
\( x = 264p + 205 \)

The smallest positive integer solution is when \( p = 0 \), which gives us \( x = 205 \).

Therefore, the smallest positive integer that leaves a remainder of 5 when divided by 8, a remainder of 1 when divided by 3, and a remainder of 7 when divided by 11 is \( \boxed{205} \).
