You can put this solution on YOUR website! Let A=30x^5z and B=45x^2yz^3. Find the greatest common factor of expression A and B.
-------------
15 is the greatest common coefficient. Any question about that?
---
The exponents of x are 5 and 2. ---> x^2
----
No y in A
-----
The exponents of z are 1 and 3 ---> 1
====================
15x^2z is the greatest common factor.
