it works well

I love this website when I'm doing m online learning since I'm in a hybrid school right now, but I love the webstie.

There is one problem with this, what if you need to find the GCF or LCM for more than two numbers? Like 234,746,175

This app is great! It helps me a lot with Greatest Common Multiples and Least Common Factors when i need it.

I absolutely hate math and i get to see my dad today because this app helped me get my homework done in time to see him.if you haven't figured it out yet my parents are divorced and i need all the time with them i can get:)
