To find the GCF of two numbers, you first split them both into their prime factors.
45 = 3x3x5
60 = 2x2x3x5
The next step is to find the common prime factors. In this case, both numbers have one 3 as a factor, and both have one 5 as a factor. To get the greatest common factor, we find the product of these common prime factors:
5x3=15
Thus the greatest common factor of 45 and 60 is 15.
