They can go into 8*4*9 = 288. That is not the smallest such number, but that was not the question.
The GCF is 2.

The least common multiple is a pretty simple process. We do this by writing down each number, and multiples of them, like this: 2 - 4, 6, 8, 10, 12 4 - 8, 12 6 - 12 Now the least common multiple is the first number that these sets share, which we see is 12, so that is the LCM (least common multiple) of these numbers.
