Factors and Prime Factorization

2
Definitions Factors ~ Whole numbers that are multiplied to find a product Factors ~ Whole numbers that are multiplied to find a product Prime Factorization ~ A number written as the product of its prime factors Prime Factorization ~ A number written as the product of its prime factors

3
Factors Begin by listing all of the factors for the number 18 1236918

4
Prime Factorization ~ Factor Tree Keep finding factors until each branch ends at a prime number. 36 218 92 33 Prime factorization of 36 is 2 2 3 3 Prime factorization of 36 is 2 2 3 3

5
Example A Find the prime factorization of 24 Use a factor tree, then write the prime factorization.

6
Example A - Answer 24 46 2 223 2 223 Prime Factorization of 24: 2 2 2 3

7
Answer A ~ Part 2 24 2 12 3 4 3 4 22 Prime factorization is the same, so even if using different numbers to do the factor tree, you will still get the same answer. 2 2 2 3 Prime factorization is the same, so even if using different numbers to do the factor tree, you will still get the same answer. 2 2 2 3
