Divide 60 by the first six counting numbers.
Find the prime factorization. Identify the distinct prime factors. Add them up.
The GCF is 12.
Divide 60 by 1, 2, 3, 4, 5 and 6.
Prime numbers have one distinct prime factor.
Not necessarily. (6,6) is a factor pair of 36, but only one of the sixes is a distinct factor of 36.
It can be. 60 is a factor of 120.
The greatest factor of a number is the number itself. So, the greatest factor of 60 is 60.
It can be. 48 is a factor of 96.
15 (45/15 =3, 60/15=4)
36
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 GCF is 12.
