The greatest common divisor and the least common multiple of two integers

The greatest common divisor (GCD) can be found using Euclidean algorithm. See description here - The greatest common divisor of two integers.

If you knew GCD, you can find the least common multiple (LCM) easily
,
where
[a,b] - LCM,
(a,b) - GCD.
