What is the prime factorization of numbers between 7-40?

Answer 1

47

Answer 2

Prime numbers don't need factorizations. That eliminates 7, 11, 13, 17, 19, 23, 29, 31, 37

2 x 2 x 2 = 8

3 x 3 = 9

2 x 5 = 10

2 x 2 x 3 = 12

2 x 7 = 14

3 x 5 = 15

2 x 2 x 2 x 2 = 16

2 x 3 x 3 = 18

2 x 2 x 5 = 20

3 x 7 = 21

2 x 11 = 22

2 x 2 x 2 x 3 = 24

5 x 5 = 25

2 x 13 = 26

3 x 3 x 3 = 27

2 x 2 x 7 = 28

2 x 3 x 5 = 30

2 x 2 x 2 x 2 x 2 = 32

3 x 11 = 33

2 x 17 = 34

5 x 7 = 35

2 x 2 x 3 x 3 = 36

2 x 19 = 38

3 x 13 = 39

2 x 2 x 2 x 5 = 40
