4 new math videos for the price of one! (Don’t worry, the price is still free.)

Factor Trees, GCF, LCM, square root, oh my!

Hi folks!

I’ve been working hard to get a video recorded and posted on a more weekly basis. Well, this week I started working on my original idea of a video about prime factorization using Factor Trees. Of course, I thought of 3 other topics factor trees are related to, so I decided to just go ahead and make a video for each of the topics! I’m sorry if by the last one I seem a little loopy. I actually get pretty nervous making these videos, and I think it started to get to me a bit after #4!

Alright then. My first video is, as I said, about factor trees. Using a factor tree is one method of finding the prime numbers that make up a composite number, i.e. 2 and 3 are both prime numbers, and when you multiply them together you get the composite number of 6. See how easy? What about finding the prime factors for 250? or 360? Lucky for you, I show you exactly how to do that in this video. Enjoy!


For my second act, I have a video that explains what LCM (Lowest Common Multiple) is and how to use factor trees to find the LCM for 2 different (larger) numbers.


Who can talk about LCM without also talking about GCF?!?!? Not this gal! Greatest Common Factor can also be found with the help of factor trees.

And last but not least, there’s good ol’ square root. Who wants to know what the square root of 225 is?!?! Anyone? Anyone?


As always, I’d love to hear from you! And share, share, SHARE!
