1 Prime Factorization 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 ÷ 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  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  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.
