Hi. The least common multiple of two or more numbers that is the smallest number (not counting zero) that is a multiple of both. So to figure the LCM of your numbers you can write them out like this:
4, 8, 12, 16, 20, 24, 28, 32, 36, 40... all the way to 108
12, 24, 36, 48, 60, 72, 96, 108
27, 54, 81, 108
The Least Common Multiple = 108
Hope this helps,
Take care,
Diana
