1. LESSON 4-3A PRIME FACTORIZATION

2. MATH VOCABULARY Prime #: A number that can only be found by multiplying the given number x 1 (only one way to get answer through multiplication) Composite #: A number that can be found by more than one way through multiplication Prime Factorization: Factoring (breaking down) a given number to only its prime numbers

3. PRIME OR COMPOSITE?? To find numbers that are prime/composite… See how many multiplication problems you can create. Prime or Composite? 33 1 x 33, 3 x 11 *Composite (more than one problem to solve) 31 1 x 31 *Prime (only one problem to solve)
