Question 148910: How would I be able to find the GCF of these groups?
1)48, 80
2)42,66,78
3)6y^2,15y^3
would this one be 3y^2
4)12a^2ab, 18ab^2,24a^3b^3
would the GCF of this group br 4ab or 6ab? Am I correct on this one?

You can put this solution on YOUR website! find the GCF of these groups?
1)48 = 2^4*3
, 80 = 2^4*5
GCF = 2^4 = 16
--------------------
2)42 = 2*3*7
,66 = 2*3*11
,78 = 2*3*13
GCF = 2*3 = 6
====================
3)6y^2 = 2*3*y^2
,15y^3 = 3*5*y^3
GCF = 3y^2
would this one be 3y^2? : Yes
-----------------------------------
4)12a^2ab = 2^2*3*a^3b
18ab^2 = 2*3^3*ab^2
24a^3b^3 = 2^3*3*a^3b^3
GCF: 2^2*3*ab = 12ab
=============================
