What does LCM mean in mathematics?

The least common multiple or LCM of two numbers 108 and 126 is defined as the smallest positive integer which is divisible by both of them. It is represented by LCM(108, 126).

Properties of LCM

The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 108 and 126 is 756, where 108 and 126 are less than 756.
LCM is associative which means LCM(108, 126) = LCM(126, 108).
LCM is commutative which means LCM(a, b, c) = LCM(LCM(a, b), c) = LCM(a, LCM(b, c)).
LCM is distributive, which means LCM(ab, bc, ad) = d * LCM(x, y, z).
The LCM of two or more prime numbers is their product.
