What is the greatest common factor of 7 - 7?

Answer 1

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.

Since 7 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 7 is 7.

You need at least two numbers to find a GCF.

Answer 2

common only applies to 2 or more numbers, 1 number can't have a common factor.

Answer 3

The GCF is 7.
