Find all the factors of each of the numbers. 25 - 1, 5, 25 35- 1, 5, 7, 35 The common factors are 1 and 5. The largest of these (5) is the GCF.
The GCF is 35.
The GCF is 7.
GCF(20, 25, 35, 40) = 5 The GCF of any set of numbers is also a factor of the difference of any pair of them. So the GCF must be a factor of 5 (= 25-20). This narrows down the options quite considerably!

The GCF of 25, 35, 1225 and 1715 = 5 The factors of 25 are 1, 5, and 25 The factors of 35 are 1, 5, 7, and 35 The factors of 1225 are 1, 5, 7, 25, 35, 49, 175, 245, and 1225 The factors of 1715 are 1, 5, 7, 35, 49, 245, 343, and 1715 GCF (35, 1715, 25, 1225) = 5
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.
The GCF is: 5
The GCF is 5.
