# Even More Fun With Prime Numbers

## Recommended Posts

This one is tougher... I believe each integer can be represented in a way so that

i = p1^e1 * p2^e2* p3^e3... * pn^en

where i is the given integer, p is a set of unique prime numbers, and e is the exponent.

For example:

1 = 2^0

2 = 2^1

3 = 3^1

4 = 2^2

5 = 5^1

6 = 2^1 * 3^1

7 = 7^1

8 = 2^3

9 = 3 ^ 2

...

96 = 2^5 * 3^1

...

160 = 2^5 * 5^1

...

115200 = 2^9 * 3^2 * 5^2

Set! Go!

No no no... this is just a nerdy way to do factor trees!

60 = 2 * 2 * 5 *3

since 2 * 2 = 2 ^2 and n^1 = n

we can write it like this

60 = 2^2 * 3^1 * 5^1

also... since n^0 = 1

we can throw in more useless numbers to make ourselves look smarter

60 = 2^2 * 3^1 * 5^1 * 7^0 * 11^0 * 13^0
