## Table of Contents

Prime numbers are numbers greater than 1 that only have two factors, 1 and the number itself. This means that a prime number is only divisible by 1 and itself. If you divide a prime number by a number other than 1 and itself, you will get a non-zero remainder.

Numbers that have more than 2 factors (but finite number of factors) are known as composite numbers.

## What is Prime Number?

A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In other words, a prime number is only divisible by 1 and itself. For example, the first six prime numbers are 2, 3, 5, 7, 11, and 13.

## How to Find Prime Numbers

1) Every prime number (except 2 and 3) can be written in the form of 6n + 1 or 6n – 1.

To check whether a given number is prime or not, you can simply check if it can be written in the form 6n + 1 or 6n – 1.
