## GCF Practice 3 - Visualizing Algebra

• 0:00 - 0:05
The greatest common factor for 15, 20 and -35 is just 5. That's going to start
• 0:05 - 0:10
the product for my GCF. Now I want to lowest factor for f that is common between
• 0:10 - 0:15
all the terms. Well, just 1 x is common between all the terms. The lowest power
• 0:15 - 0:19
of Y that is common is 2. So y squared would also appear in my GCF. An finally,
• 0:19 - 0:24
I look at the lowest power of Z between all of the terms, but I have to be
• 0:24 - 0:29
careful. There's no z over here. So z won't be included in my GCF. So a factor
• 0:29 - 0:33
of 5x y squared from each of these terms. I need 3x y squared z cubed for the
• 0:33 - 0:39
first term. 4z to the fifth of the second term and negative x squared y for the
• 0:39 - 0:43
last term. I can do this pretty quickly if just check the multiplication as I
• 0:43 - 0:48
go. 5 times 3 is 15. X times x is x squared, and y squared times y squared is y
• 0:48 - 0:53
to the 4th. Of course, I also have this z cubed on the end. So this is my first
• 0:53 - 0:58
term. When I multiply these two terms together, I get 20xy squared z to the
• 0:58 - 1:02
fifth. The variables are just listed are multiplied together. And 5 times 4 is
• 1:02 - 1:07
20. Finally, I know this last term must be correct. 5 times negative 7 is
• 1:07 - 1:13
negative 35, and x times x squared is x cubed. The last variable is y cubed,
• 1:13 - 1:18
which comes from y squared times y. So yeah, this is definitely my factored
• 1:18 - 1:18
form.
