How do you find the gcf

1).  List all the factors of the first number.

2).  List all the factors of the second number.

3).  Make a "short list", of the factors that are on both lists.
     These are the 'common' factors.

4).  Find the biggest number on the short list.
     That's the 'greatest common factor' of the original two numbers.
