Remember what a FACTOR is?? It's a number that divides evenly into another number!

For example: 1, 2, 3, 6 are all FACTORS of the number 6.
FACTOR PAIRS: 1 x 6, 2 x 3
Here is a factor rainbow!

MULTIPLES are #'s that we land on when we SKIP COUNT by a number.

For Example, the first 5 MULTIPLES of 5 are 5, 10, 15, 20, 25

Finding the GCF (Greatest Common Factor) requires 2 numbers...

Step 1: Find ALL the factors of BOTH numbers.
Step 2: Circle all the COMMON FACTORS.
Step 3: The GCF is the LARGEST common factor.

The LCM (Least Common Multiple) also requires 2 numbers...
Step 1: List the multiple of the first number until you find a multiple the second number shares.
Step 2: List the multiple of the second number until you find a common multiple.
Step 3: Once you come across a common multiple, that is the LCM.

Exponents can be a little confusing. Usually it's figuring out the STANDARD FORM that poses a problem for our students.
