Learn how to find the greatest common divisor (GCD) of two numbers using three different algorithms: the Euclidean, the binary, and the Lehmer's algorithm.

The algorithm is based on the observation that the GCD of two numbers does not change if the smaller number is subtracted from the larger number repeatedly. The process is repeated until both numbers ...
