GCF Involving Variables
For each example, find the GCF.
Sample A
-18y^2, -63y^3, 27y^4
So, the biggest number that evenly divides -18, -63 and 27 is 9.
The biggest variable term that evenly divides y^2, y^3 and y^4 is y^2.
The GCF is 9y^2.
You say?
Sample B
4x^2, x^3, 3x^6
Let me see. I say that 1 is the only coefficient in this example that evenly divides 1, 3, and 4.
With respect to the variables, x^2 evenly divides into x^2, x^3, and x^6.
The GCF is 1•x^2 or simply x^2.
You say?
The Rapture is the central event in biblical prophecy. The greatest truth about the Rapture is not its timing but it's reality. The Rapture will be the great disappearance.

It certainly feels good to know that I am right this time around. Math helps keep my brain cells alive. No pun intended.
