**Find the prime factorization of 30**

Draw two “branches” off of the number. 30

3
**Find the prime factorization of 30**

Write two numbers that are factors of 30. *Remember: factors are the numbers multiplied together 30 6 5

4
**Find the prime factorization of 30**

Determine if the first number is prime or composite. (if don’t know definitions, click on the word.) 30 6 5

5
**Prime The only factors of the integer are itself and one.**

EX: *1 EX: * 1

6
**Composite There are many factors for the integer.**

EX: *24; 2*12; 3*8; 4*6 EX: *32; 2*16; 4*8

7
**Find the prime factorization of 30**

Notice the 6 is NOT PRIME. It is composite. So, Draw two “branches” off of the number and write two factors of six at the end of each branch. 30 6 5 2 3

8
**Find the prime factorization of 30**

The number 5 is prime, so there is no need to draw branches from it. Just circle the number. 30 6 5 2 3

9
**Find the prime factorization of 30**

The number 2 is prime, so there is no need to draw branches from it. Just circle the number. 30 6 5 2 3

10
**Find the prime factorization of 30**

The number 3 is prime, so there is no need to draw branches from it. Just circle the number. 30 6 5 2 3

11
**Find the prime factorization of 30**

Now that all numbers are prime, write the prime factorization of 30. 2 * 3 *5 30 6 5 2 3

Prime Factorization The list of prime factors in numerical order as products of each other.

13
**Find the prime factorization of 81**

Draw two “branches” off of the number. 81

14
**Find the prime factorization of 81**

Write two numbers that are factors of 81. 81 9

15
**Find the prime factorization of 81**

Determine if the first number is prime or composite. 81 9 9

16
**Find the prime factorization of 81**

Notice the 9 is NOT PRIME. It is composite. So, Draw two “branches” off of the number and write two factors of nine at the end of each branch. 81 9 9 3 3

17
**Find the prime factorization of 81**

The number 3 is prime, circle the numbers. 81 9 9 3 3

18
**Find the prime factorization of 81**

The number 9 is not prime, so we need to draw branches of the number nine. 81 9 3

19
**Find the prime factorization of 81**

Now that all numbers are prime, write the prime factorization. 3 * 3 * 3 * 3 or 34 81 9 3

20
**Find the prime factorization.**
