Least Common Multiple

LCM

A smallest common multiple of two or more integers.

In general, Least Common Multiple (LCM) is otherwise called as Lowest Common Multiple (LCM) or Smallest Common Multiple (SCM)

How to Find LCM

3 and 6

In this example, we will find the least common multiple of 3 and 6

3 = 3, 6, 9, 12, 15 ... N

6 = 6, 12, 18, 24, ... N

Clearly, 6 is the least common multiples of 3 and 6.

5 and 7

In this example, we will find the least common multiple of 5 and 7

5 = 5, 10, 15, 20, 25, 30, 35, 40... N

7 = 7, 14, 21, 28, 35, 42, 49, 56 ... N

Clearly, 35 is the least common multiples of 5 and 7.
