if they have no obvious common factors (such as 3!!!!!!!) then you multiply them to get the GCF.

60, 72, 84, 90 and 96 each have twelve factors.
The greatest common factor of 36, 48, and 72 is twelve (12).
0.8
Three
1
60,120,180 and multiples of 60
Since 12 is a factor or 36, it is automatically the GCF.
Twelve
The Least Common Multiple (LCM) for 12 15 is 60
The greatest common factor between twelve and eight is four. Don't get confused about greatest common factor and greatest common multiple. There is GCF and GCM, be sure to pay extra attention to the last letter or word, whichevere form it is in.
1,2,4,7,9
The answer is 4.

12, 24 Factors of 12 = 1, 2, 3, 4, 6, 12 Factors of 24 = 1,2,3,4,6,8,12, 24
