Example 1:

Find the least common multiples of 2 and 3

The multiples of 2 are: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24

The multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, and 36

Thus the common multiples of 2 and three are 6, 12, 18 and 24

 

The smallest of these multiple s(i.e. the least) is 6

We say that the least common multiple of 2 and 3 is 6.

That is L.C.M of 2 and 3 is 6
