What is the greatest common factor of 4?

Answer 1

You need at least two numbers to find a GCF.

The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.

The factors of 4 are 1, 2 and 4.

Answer 2

This question cannot be answered as is. To have a GCF (greatest common factor), you need to have two or more numbers so that you can find what is common between them.

Answer 3

There cannot be a common or greatest common factor of just one number. You need two or more numbers.

Answer 4

It is not possible to give a sensible answer to this question. The greatest common factor refers to a factor that is COMMON to two or more numbers. You have only one number in the question!
