Computing the Greatest Common Divisor with the Euclidean Algorithm
The greatest common divisor (GCD) of two or more integers is the largest positive integer that divides each of the numbers without leaving a remainder. For instance, the common divisors of 12 and 18 are 1, 2, 3, and 6. The largest among them is 6, so gcd(12, 18) = 6. This concept is fundamental in a...
