Hello,
I am a teacher checking out your website. It is great.
But this problem doesn't really work in my mind. If there are 15 identical eraser and 20 identical folders, one can actually create 15 identical folder/eraser sets. I don't think this question calls for GCD like it is meant to.
Thanks for your hard work!
Joel
