1. SWBAT find the prime factorization of a number.

2. Warm Up
1. Find the GCF of 50 and Plot the point (6, 2) on a coordinate plane. 3. Solve: 2394 ÷ 17

3. Vocab What is a prime number? What does it mean to “factor”
Prime Factorization: Finding which prime numbers multiply together to equal a particular number
We factor these prime numbers out just like the factor ladder, or we can use a factor tree

4. Rules Each number only has ONE prime factorization.
Since 1 is neither prime nor composite, we do not use 1 in our factor string
List the numbers from LEAST to GREATEST
Numbers that occur more than once can be shown using exponents
Exponent: Shows how many times to multiply the base times itself

5. Example
Prime factorization of 24

6. Your Turn!
Work independently on the worksheet. The top of the sheet gives further explanation, so make sure you read over it.

7. Exit Ticket What is a prime number?
Find the prime factorization of 60.
