The best way to do this is to find the LCM of the highest 2 numbers (a) and (b) and then work with the last (c) relative to the LCM of (a) and (b).
LCM(a,b) = (ab)/(gcf(a,b))
12 factors to [2 2 3]
15 factors to [3 5]
common factor is [3]
LCM(12,15) = (12)(15)/3 = 60
Happily, 10 is a factor of 60, so 60 is the LCM(10,60) and you are done here.
60 is the answer.◄
If you want to work it all the way out...
10 factors to [2 5]
60 factors to [2 2 3 5]
common factors are [2 5]
LCM(10,60) = (10)(60)/(10) = 60
If you follow the formula, it will always work.
