Prime factorize the two numbers:
666 = 2 x 3 x 3 x 37
888 = 2 x 2 x 2 x 3 x 37
Notice I lined up all the numbers into columns. If they appear for both numbers they are paired. The lowest common multiple is the product of all the unique columns:
LCM = 2 x 2 x 2 x 3 x 3 x 37 = 2664
You can use this strategy for as many numbers as you want. Also, you could find the greatest common factor by multiplying only the paired columns.
It would be 3.5 x 10 to the -3 power.
Hope it helps ;-)
