The Greatest Common Divisor (GCD) of 25 and 55 can be found by identifying the largest number that divides both without a remainder. Listing factors of 25 (1, 5, 25) and 55 (1, 5, 11, 55) shows the common factors are 1 and 5, with 5 being the greatest. Using the Euclidean algorithm: divide 55 by 25, yielding a remainder of 5. Then divide 25 by 5, resulting in a remainder of 0. The last non-zero remainder is the GCD, which is 5.

deepseekv3 To find the **GCD (Greatest Common Divisor)** of 25 and 55, we can use the **prime factorization** method.

1. **Factorize the numbers:**
- \( 25 = 5 \times 5 \)
- \( 55 = 5 \times 11 \)

2. **Identify the common factors:**
- Both numbers share the factor **5**.

3. **Determine the GCD:**
- The greatest common divisor is the product of the common prime factors, which is **5**.

**Answer:** A. 5
