Prime Number Calculation Formula. The formula for checking if a number is prime is quite simple: a number is prime if it has exactly two distinct divisors: 1 and itself. Here’s a simple code to check for prime numbers: def isPrime(n): if n <= 1: return False.
This function checks if a given number n is prime or not using trial division method, which involves dividing n by all integers from 2 up to the square root of n. If no divisors are found within that range, the number is prime.
