**GCF**

Yesterday, factoring was a hard game to play,

Now I see things in a different way,

Oh, I believe in GCF!

Suddenly, factoring is not a mystery!

I’m getting A’s so easily,

All because of GCF!

First, list all the prime factors, using factor trees.

Next, just multiply common factors don’t you see (ee-ee-ee).

But you see, common factors may just not appear!

In that case you have no work to do,

For the GCF is 1.

How did I exist knowing little, not so deft?

Now, there’s this magic thing that they call the GCF! (ef-ef-ef)

Now I say, “GCF beats every other way!”

Common factors is a game I play,

Oh I believe in GCF!

I believe in GCF!
