What does LCM mean in mathematics?

The least common multiple or LCM of two numbers 128 and 192 is defined as the smallest positive integer which is divisible by both of them. It is represented by LCM(128, 192).

Properties of LCM

The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 128 and 192 is 384, where 128 and 192 are less than 384.
LCM is associative which means LCM(128, 192) = LCM(192, 128).
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.
