What is the least common multiple of 30 and 12?

Answer 1

The Least Common Multiple (LCM) of (12,30) is 60.

The lowest common multiple for two numbers can be calculated by:

1. Considering the relationship as a ratio.

2. Simplifying the ratio (if possible)

3. multiplying each original number by the "opposite" ratio.

So 12 and 30 are in the ratio of 12 to 30, that is 12:30. This can be simplified to 2:5. You will notice that if we now multiply the 12 by the 5 and the 30 by the 2 we will reach the same answer of 60. 60 is therefore the LCM.
