PrimeChecker

A simple Python function that checks if an odd number is prime using a custom formula.

How to Use

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
