Greatest Common Factors 7

Now, we shift two numbers down and do it again:

16 = 2 * 6 + 4 ... 2 ) 6 = 1 * 4 + 2 ... 4 goes into 6 one time ... with 2 left over

OK, let me write this out in one chunk:

Find

16 = 2 * 6 + 4 ... 6 = 1 * 4 + 2 ... this 2 is the GCF ... 4 = 2 * 2 + 0 ... when you hit + 0, you are done!

The GCF is always the last remainder before you get 0!
