# PrimeChecker
A simple Python function that checks if an odd number is prime using a custom formula.
## How to Use
```python
from PrimeCheck import PrimeCheck
number = 17
is_prime = PrimeCheck(number) # Returns True
```
## How it Works
Uses the formula: `(((n-1)/2)-a) / ((2*a)+1)`
- If the formula ever results in a whole number, the input is not prime
- Otherwise, the number is prime
