Use the Euclidean algorithm to find gcd (1000, 5040)

To find the greatest common divisor (GCD) of 1000 and 5040 using the Euclidean algorithm, we proceed as follows:

1. **Apply the Euclidean algorithm:**
   - Divide the larger number by the smaller number and find the remainder.
   - Replace the larger number with the smaller number, and the smaller number with the remainder.
   - Repeat this process until the remainder is 0. The last non-zero remainder is the GCD.

Let's perform these steps:

\[
5040 \div 1000 = 5 \quad \text{(quotient)} \quad \text{remainder} = 5040 - 5 \times 1000 = 5040 - 5000 = 40
\]

So, we now replace 5040 with 1000 and 1000 with 40.

\[
1000 \div 40 = 25 \quad \text{(quotient)} \quad \text{remainder} = 1000 - 25 \times 40 = 1000 - 1000 = 0
\]

Since the remainder is now 0, the last non-zero remainder is 40. 

Therefore, **GCD(1000, 5040) = 40**.
