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.
