Greatest common divisor is found with the Euclidean algorithm (repeatedly replacing the larger number with the remainder of dividing it by the smaller, until the remainder is 0) — the fastest standard method for computing a GCD. Least common multiple is then derived from GCD using LCM = |a × b| ÷ GCD.
