For smaller numbers you can simply look at the factors or multiples for each number and find the greatest common multiple of them. Euclidean Algorithm. In Euclid's algorithm, we start with two numbers X and Y.If Y is zero then the greatest common divisor of both will be X, but if Y is not zero then we assign the Y to X and Y becomes X%Y.Once again we check if Y is zero, if yes then we have our greatest common divisor or GCD otherwise we keep continue like this until Y becomes zero. It is the greatest number you can multiply to get all the numbers. Extended Euclidean algorithm This calculator implements Extended Euclidean algorithm, which computes, besides the greatest common divisor of integers a and b, the coefficients of Bézout's identity This site already has The greatest common divisor of two integers, which uses the Euclidean algorithm.
