What is the least common multiple of 9 and 6 and 12?

Answer 1

We can find the least common multiple by writing out each of these numbers, and writing their multiples, like this:

6 - 12, 18, 24, 30, 36

9 - 18, 27, 36

12 - 24, 36

Now we look and see what the lowest number that all three of these numbers have multiples of. We can see that the least common multiple of these numbers is 36, so this our answer.
