Factoring Whole Numbers Factors – are numbers that are multiplied to get a product. 1. What are the factors of 16? 1 x 16 = 16 2 x 8 = 16 4 x 4 = 16 Factors of 16: 1, 2, 4, 8, 16 2. What are the factors of 24? 1 x 24 = 24 2 x 12 = 24 3 x 8 = 24 4 x 6 = 24...
Factoring Whole Numbers Factors – are numbers that are multiplied to get a product. 1. What are the factors of 16? 1 x 16 = 16 2 x 8 = 16 4 x 4 = 16 Factors of 16: 1, 2, 4, 8, 16 2. What are the factors of 24? 1 x 24 = 24 2 x 12 = 24 3 x 8 = 24 4 x 6 = 24 Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24 Remember This Factors are numbers that we multiply to get the product. 1 and the number being factored are always factors of the given number. 0 is a factor of itself. Try This! Directions: List all the factors of the given numbers. 1, 2, 3, 6, 9, 18 1. 18 = ______________________ 1, 2, 4, 5, 2. 20 = 10, 20 ______________________ 1, 3, 5, 15 3. 15 = ______________________ 1, 5 4. 5 = ______________________ 1 , 11 5. 11 = ______________________ Remember This Prime numbers are numbers with only two factors: one and the number itself. Composite numbers have more than two factors.
