The Euclidean Algorithm

The Euclidean algorithm is a method for finding the greatest common divisor (GCD) of two integers. Here’s how it works:

Step 1: Take two integers, (assumed to be greater than or equal to ) and .
Step 2: Compute the remainder of divided by using the division algorithm: .
Step 3: Replace with and with . Essentially, set and .
Step 4: Repeat the process (Step 2 and 3) until becomes zero.
Step 5: The GCD of the original two numbers and is the non-zero value of when the
