  8. {

What is the formula for finding prime numbers?

Method 1: Two consecutive numbers which are natural numbers and prime numbers are 2 and 3. Apart from 2 and 3, every prime number can be written in the form of 6n + 1 or 6n – 1, where n is a natural number. Note: These both are the general formula to find the prime numbers.
