Get the GCF for these two numbers, your teacher says.
How, you ask.
Easy, your teacher replies. Do what I told you yesterday.
But let’s say you don’t remember. Or let’s say you don’t like the technique your teacher used, telling you to prime factorize the numbers … well then you’re in luck because I’m going to show you another way to find the GCF, one that is 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.
