What is the greatest common factor of 4xy^2 and 20x^2y^4

Answer:
greatest common factor is 4xy^2
Step-by-step explanation:
the greatest common factor of 4xy^2 and 20x^2y^4
BReak the factors for each term
4xy^2 ---> 2*2*x*y*y
20x^2y^4 -----> 2*2*5*x*x*y*y*y*y
Now we look at the common factors for both terms
2*2*x*y*y. Multiply it to get GCF
So greatest common factor is 4xy^2
