What is the LCM of 18 and 270 - Find out answer step by step

What does LCM mean in mathematics?

The least common multiple or LCM of two numbers 18 and 270 is defined as the smallest positive integer which is divisible by both of them. It is represented by LCM(18, 270).

Properties of LCM

LCM follows associative property, that means LCM(18, 270) = LCM(270, 18).
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 18 and 270 is 270, where 18 and 270 are less than 270.
The LCM of two or more prime numbers is their product.
