What is the LCM of 140 and 112 - Find out answer step by step

Definition of LCM

LCM stands for least common multiple. In mathematics, LCM of two numbers 140 and 112, is defined as the smallest positive integer that is divisible by both. It is written as LCM(140, 112).

Properties of LCM

The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 140 and 112 is 560, where 140 and 112 are less than 560.
LCM is associative which means LCM(140, 112) = LCM(112, 140).
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.
