Highest common factor of 84

Answer 1

84 x 1 = 84

GF = 84

Actually, it is not possible to give a sensible answer to this question. 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!

Answer 2

There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

Answer 3

The GCF of 64 and 84 is 4.

The factors of 64 are: 1, 2, 4, 8, 16, 32, 64.

The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.

The common factors are: 1, 2, 4.

The Greatest Common Factor (GCF) is: 4

Answer 4

The Greatest Common Factor of 42 and 84 is 42.

Answer 5

the GCF is 4
