Well, honey, the two numbers that have a Greatest Common Factor (GCF) of 4 are any multiples of 4. So, for example, 4 and 8, 12 and 16, or even 20 and 24 would do the trick. Just pick any two numbers that both have 4 as a factor, and you're good to go.

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 4.
An interesting trick is to subtract the two numbers, as follows: For example, the GCF of 14 and 10 is the same as the GCF of 10 and 4, where 4 is the result of the subtraction. Instead of subtracting several times, you can also get the remainder of a division: 10 divided by 4 gives a remainder of 2.
