Find the LCM of the top two first, then take that answer and find the LCM of that and the smallest number.LCM is the product divided by the GCF15 factors to [3 5]22 factors to [2 11]No common factorsLCM = 15 * 22 = 330330 factors to [2 3 5 11]12 factors to [2 2 3]common factors are [2 3] GCF=6LCM = 330 * 12 / 6 = 660 ■
The common factors are: 1, 2, 3, 4, 6, 12.
