“Get the GCF for these two numbers,” your teacher says.

“How?” you ask.

“Easy,” your teacher replies. “Do what I told you yesterday.”

But perhaps you don’t remember. Or maybe you don’t like the technique your teacher used, telling you to prime factorize the numbers …

Even though that felt awful, now you’re in luck because I’m going to show you another way to find the GCF, one that’s more intuitive and easier than the prime factoring technique. So just sit back and watch the following video. Then do the practice problems at the end of the video. And you’ll know something that even your teacher probably doesn’t know … a thoroughly original way to find the GCF of two numbers.
