Question

take out the largetst common factor

1) 10584h(superscript3)k - 1680hk(superscript4)

thanks

Answer 1

168hk

Find the greatest common factor between 10584 and 1680.

10584 = 2 * 3 * 4 * 7 * 7 * 9
1680 = 2 * 2 * 3 * 4 * 5 * 7

Common factors are 2 * 3 * 4 * 7 =168

Common factor between h^3 and h is h
Common factor between k and k^4 is k

That leaves you with

168hk(63h^2 - 10k^3)

Answer 2

Is this the problem: 10584h^3 times k - 1680hk^4

an h and k are common factors.
Then look for GCF of 10584 and 1680 which I believe is 24. You can find this by dividing each number by the same and multiplying your factors together.

Therefore this can be rewritten as 24hk(441h^2 - 70k^3)
