Question

Find the first three common multiples of $12,18$

Answer 1

Write down the multiples of $12$ and $18$ and identify the common one

A common multiple refers to a multiple of one or more than one number.

First ten multiple of $12$ is $=12,24,36,48,60,72,84,96,108,120$

First ten multiple of $18$ is$=18,36,54,72,90,108,126,144,162,180$

The common multiple of $12$ and $18$ in their first ten multiples are $36,72$ and $108$

Hence, the first three common multiples of $12$ and $18$ are $36,72$ and $108$
