## Examples showing how to find the common multiple of two or three numbers

**Example #1**

Find the common multiple of 6 and 8.

First, list the multiples of each number. In our example here, we will show only the first 13 multiples of each number.

Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, ...

Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, ...

As shown in red, the first three common multiples of 6 and 8 are 24, 48, and 72.

Notice that 6 and 8 have a lot more common multiples than just 24, 48, and 72. Just keep listing more and more multiples of each number and you will find more common multiples.

**Example #2**
