How do you get the greatest common factor of 75 150 and 225?

Answer 1

Since 75 is a factor of itself and of both 150 and 225, it will automatically be the GCF of this set.

One correct way to do it is through prime factorization.

3 x 5 x 5 = 75

2 x 3 x 5 x 5 = 150

3 x 3 x 5 x 5 = 225

Select the common factors.

3 x 5 x 5 = 75, the GCF.

Answer 2

The GCF is 15.

Answer 3

It is: 5
