1
Write factor pairs for each number. Use divisibility tests to help you! x 40 2 x 20 4 x 10 5 x 8 1 x 72 2 x 36 3 x 24 4 x 18 6 x 12 1 x 57 3 x 19 8 x 9

2
Write factor pairs for each number. Use divisibility tests to help you! x 12 2 x 6 3 x 4 1 x 20 2 x 10 4 x 5 1 x PRIME

3
PRIME NUMBERS A whole number with exactly 2 factors, 1 and itself

4
Make a prime factor tree for each number x 2x22x3x 6x10 2x32x5x 24 = 2 x 2 x 2 x 3 24 = 2 3 x 3 60 = 2 x 2 x 3 x 5 60 = 2 2 x 3 x 5

5
You can use prime factorizations to find the GCF or to simplify fractions x 2x22x3x 6x10 2x32x5x x 2 x 2 x 3 2 x 2 x 3 x GCF 2 x 2 x 3 = 12

6
Make a prime factor tree for each number to find the GCF x 2x32x3x 6x9 2x33x3x 36 = 2 x 2 x 3 x 3 54 = 2 x 3 x 3 x 3 GCF 2 x 3 x 3 = 18

7
Make prime factor trees for each number. Use the prime factorizations to find the GCF and to simplify the fraction x 2x22x5x 2x28 2x2 4x x 2 x 2 x 5 2 x 2 x 2 x GCF 2 x 2 x 2 = 8 ==

8
List the factors of x 15 3 x 5 List the multiples of , 30, 45, 60, 75, …

9
List the first 5 multiples of each number , 24, 36, 48, 60 16, 32, 48, 64, , 48, 72, 96, 120

10
Use the LCM to get a common denominator , 24, 36, 48, 60 16, 32, 48, 64, , 48, 72, 96, = = 28 15

11
Use the LCM to get a common denominator , 24, 36, 48, 60 16, 32, 48, 64, , 48, 72, 96, = = 18 15

12
Use the LCM to get a common denominator , 24, 36, 48, 60 16, 32, 48, 64, , 48, 72, 96, = = 10 11

13
List the factors of x 32 2 x 16 4 x 8

14
Make a prime factor tree for x 2x22x4 2x16 2x2 4x4 32 = 2 x 2 x 2 x 2 x 2 32 = 2 5 2x22x2x

15
Use the prime factorization to simplify x 2x3 2x16 2x2 4x4 12 = 2 x 2 x 3 2x2x = 2 x 2 x 2 x 2 x What is the GCF? 4

16
List factor pairs to find the GCF x 18 2 x 9 3 x 6 1 x 30 2 x 15 3 x 10 5 x 6 Use the GCF to simplify: ÷ 6 GCF =

17
Write the expressions using exponents. 2 x 3 x 3 x 5 x 5 = 5 x 5 x 5 x 7 x 7 = 2 x 3 2 x x 7 2

18
Find the LCM. 8 8, 16, 24, 32, 40 10, 20, 30, = = 15 16
