ʕ•ᴥ•ʔ Polynomial Factoring with the Greatest Common Factor (GCF) w/ examples 1

Quickly master how to factor with the greatest common factor (GCF).

You will need the similar skill set to find the common factors of polynomials as you do prime factorization. For polynomials, you need to also do the numbers as well as the variables.

Hi! Welcome to this question right here. So we're trying to find the common factor of these three different terms. So you just have to think "Okay. What are the things that they have in common?" right? So here we go. The first one right here. So I've got a 16, an 8 and a 4. So maybe I can take the 4 out of every single one of them. That means you're dividing he 4 from each. So 16 divided by 4. We've got 4 for the first one, we also have 2 for the second one and we've got just 1 left over for the third person. Is there anything else we can take our from each? Okay. It seems that the first one has a to the power of 4, a to the power of 3, a to the power of 2. So you pick the highest common factor that they have. I believe it is called the GCF, the greatest common factor. So a 4, a 3, a 2. You can take out a to the power of 2. So the common factor that we have is 4 a squared on the outside. So if you take the a at the power of 4. If you take the a square out, meaning that if you divide it by a square you only have a square left over. And minus just one a left over here and a plus. This one is entirely taken out. So it's just a 1 left over. So this is your final answer. Okay? Thanks for watching!
