So now we need the greatest common factor of 20, y to the third, 30 y to the fourth, and 40 y to the 6th.
00:20
So if we want to do that, we want to list out our factors first to see what we have going on.
00:25
So we're going to do our prime factorization first.
00:28
Then we're going to look for common factors, and then we're going to find our greatest common factor.
00:33
So factored form, 20 is 2 times 10, so that's 2 times 2 times 5, and y cubed means that there are 3 ys as factors as well.
00:48
For 30, we have 3 times 10, so that's 3 times 2 times 5, and we have 4 y's this time.
01:02
For 40 y to the 6, it's going to be 4 times 10, which 4 is 2 times 2.
01:09
And then we have our two times five and six wise...
