TRUE or FALSE?

A FACTOR is greater than the number you are factoring

• TRUE

• FALSE

Draw a Venn Diagram on your paper like this one.

Using your factor trees, list the SHARED multiples of 36 and 100.

The shared factors are ​​​ (a)   and ​ (b)   . This means that the GCF is the product of those factors, or ​ (c)   .

• 2

• 3

• 5

• 7

• 11

• 4

• 8

• 12

Create the correct distributive property expression for 18 + 24 by factoring out the GCF from the last question.

Hint: Write down the correct answer on your paper. Start with the GCF outside the parenthesis.
