Question

What are the greatest common factors of 12,60,102

Answer 1

well what are the factors of each?

12 = 2*2*3

60 = 2*2*3*5

102 = 2*3*17

so take the one they have in common, 2*3 = 6

Answer 2

First, lets factor these.
12:1,2,3,4,6,12
60:1,2,3,4,5,6,10,12,15,20,30,60
102:1,2,3,6,17,34,51,102

The greatest one in common is 6.

Answer 3

should there be more than one? because if the answer is factorS then you're probably looking for the greatest common prime factors.. which would just be 2 and 3.
