What is the LCM of 210 and 240 - Find out answer step by step

Definition of LCM

LCM stands for least common multiple. In mathematics, LCM of two numbers 210 and 240, is defined as the smallest positive integer that is divisible by both. It is written as LCM(210, 240).

Properties of LCM

LCM follows associative property, that means LCM(210, 240) = LCM(240, 210).
LCM follows commutative property, which means LCM(a, b, c) = LCM(LCM(a, b), c) = LCM(a, LCM(b, c)).
LCM follows distributive property, which means LCM(ab, bc, ad) = d * LCM(x, y, z).
The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 210 and 240 is 1680, where 210 and 240 are less than 1680.
The LCM of two or more prime numbers is their product.
