Question 177741: I have a two part question. I have done these and I would like to know if I got them correct. 1. I need to find the GCF for 18u^7w^2y and 26wy. I came up with 2.
The next part is the LCM for 4t^2w^3x^6 and 16t^7x^5 and got 16t^7w^3x^6 for the lcm. Right or wrong?Thanks in advance, Judy

1.

You're on the right track, but you need to include the variable portions as well. Since both terms have a "w" and a "y" in commmon, this means that the variable portion of the GCF is wy.

So the GCF of 18u%5E7w%5E2y and 26wy is 2wy

2.

You are correct.

Find the Greatest Common Factor:

has: 1 factor of 2, 2 factors of 3, 7 factors of u, 2 factors of w, and 1 factor of y.


has: 1 factor of 2, 1 factor of 13, 1 factor of w, and 1 factor of y

The smallest number of factors of 2 is 1 (they both have 1 factor of 2)

The smallest number of factors of 3 is 0 (one has 0 factors of 3)

The smallest number of factors of 13 is 0 (one has 0 factors of 13)

The smallest number of factors of u is 0 (one has 0 factors of u)

The smallest number of factors of w is 1 (one has 1, the other has 2)

The smallest number of factors of y is 1 (they both have 1 factor of y)

In sum, you need 1 factor of 2, 1 factor of w, and 1 factor of y to make the GCF, hence:
