**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**

**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**

**multipl**

**e th**

**e 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.**
