Now that we know the factors of 16 and 24, which one is the greatest?

• 24

• 16

• 12

• 8

When you divide the greatest common factor (GCF) from both 16 and 24, what two values remain?

• 2

• 3

• 4

• 1

What is the greatest common factor (GCF) between 100 and 75?

If you need to, list out the factors, maybe a table helps like you see at left.

• 5

• 10

• 15

• 25

When you divide out the GCF from 75 and 100, what two numbers remain?

• 2

• 3

• 4

• 5

Let's use some variables.

Find the GCF between x⁷ and x¹⁰ .

Remember that powers are repeated multiplication. If you need to, write out the repeated multiplication for both and see how many are common.

• x⁷

• x

• x¹⁰

• I still need a little help here.

How about this one...

Find the GCF between xy² and x³y⁵.

• xy²

• x³

• y⁵

• I still need a little help here.

One more step up before the "test."

What is the GCF between 5x⁴y³ and 10x²y² ?

• 2xy

• 5xy

• 5x²y²

• I need a lot of help with this one.

The test!

Which of the following is equivalent (or equal) to 4x³y⁵ + 6xy³?

• 2xy³

• 2xy³ (2x²y² + 3)

• 2xy³ (2x²y² + 6xy³)

• Yep, you got me, not sure.
