Question

What is the least common multiple of 12, 13, and 6?

Answer 1

`156`

Explanation:

First, factor each number into its prime factors:

`12=2^2*3`
`13=13`
`6=2*3`

Now, you must multiply the different factors, but only the ones with the highest exponent.

`lcm=2^2*3*13=156`

The lowest common multiple is `156`
