The least common multiple (LCM) of 2, 8, and 12 is 24. To find the LCM, prime factorize each number.

2=2

8=2*2*2

12=2*2*3

Multiply each factor the greatest number of times it occurs in any of the numbers. 8 has the most twos, so take three 2s. 12 has one 3.

2*2*2*3=24

So 24 is the lowest common multiple of 2, 8, and 12.
