find the greatest common factor of these expressions

20v^7 u^3 and 16x^6 v^4 u^5

2 answers

what I see as common is

4 u^3 v^4
20 v^7 u^3
16 x^6 v^4 u^5
GCF of 16 and 20: 4
GCF of v^7 and v^4 : v^4
GCF of u^3 and u^5 : u^3

Thus, the GCF is the product of the three, which is equal to 4 v^4 u^3.

hope this helps :3
