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 greatest common factor of 72 and 210 is 6

There cannot be a common or greatest common factor of just one number. You need two or more numbers. If that's 2 and 10, the GCF is 2.

Since 2 is a factor of 72, it is automatically the GCF.
