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.
The Greatest Common Factor (GCF) is: 15
15
The highest common integral factor is 5, because 25 = 52, five is an integral factor of both 45 and 60, and 25 is not an integral factor of either 45 or 60.
The GCF is 5.
The Greatest Common Factor of 60, 45, and 30 is 15.
the GCF of 45 and 60 is 15
