The GCF of 24 and 72 is 24

First find all the prime factors for each number.

24: 2 x 2 x 2 x 3

72: 2 x 2 x 2 x 3 x 3

Next find all the prime factors common to both numbers in this case it will be the following:

GCF: 2 x 2 x 2 x 3 = 24

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

Factors of 72 include 1,2,3,4,6,8,9,12,18,24,36,72

Therefore the greatest common factor of 24 and 72 is 24.

Since 24 is a factor of 72, it is automatically the GCF.
