What is the LCM of 135 and 75 - Find out answer step by step

Definition of LCM

LCM stands for least common multiple. In mathematics, LCM of two numbers 135 and 75, is defined as the smallest positive integer that is divisible by both. It is written as LCM(135, 75).

Properties of LCM

The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 135 and 75 is 675, where 135 and 75 are less than 675.
LCM is commutative which means LCM(a, b, c) = LCM(LCM(a, b), c) = LCM(a, LCM(b, c)).
The LCM of two or more prime numbers is exactly equal to their product.
LCM is associative which means LCM(135, 75) = LCM(75, 135).
LCM is distributive, which means LCM(ab, bc, ad) = d * LCM(x, y, z).
