What is the LCM of 12 and 162 - Find out answer step by step

How do we define LCM?

LCM, abbreviation for least common multiple, is defined as the smallest number that is the product of two or more numbers 12 and 162

Properties of LCM

The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 12 and 162 is 324, where 12 and 162 are less than 324.
LCM is associative which means LCM(12, 162) = LCM(162, 12).
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.
