How can you write 128 as a product of prime number?

Divid 128 repeatedly by the smallest prime numbers you can find until you get to 1. Like this:


128 / 2

64 / 2
32 / 2
16 / 2
8 / 2
4 / 2
2 / 2

You can see from this that the only prime factor of 128 is 2

Answer 2

128/2 = 64

64/2 = 32

32/2 = 16

16/2 = 8

8/2 = 4

4/2 = 2

2/2 = 1

128 = 27

Answer 3

1, 2, 4, 8, 16, 32, 64, 128

Just make a T graph

1 .... 128

2 .... 64

3 .... none

4 .... 32

etc.
