2
What are factors? Factors are whole numbers multiplied together to make a product. (A number is divisible by its factors.) 2 x 3 = 6 product factors

3
**Example 1: List all the factors of each number.**

18 1 x 18 Start by listing all 2 x 9 the pairs of factors 3 x 6 The factors of 18 are: 1, 2, 3, 6, 9, and 18

6
**Example 2: Write the prime factorization of each number.**

Use a factor tree: 36 *Start with any two factors you think of * then keep using factors until you get only primes The prime factorization of 36 is: 22.32

7
**Example 2: Write the prime factorization of each number.**
