When any number is divisible only by one and itself, i.e. the number has only two factors, then it is called a prime number. A prime number cannot be factorized because it does not have factors other than 1 and the number itself. The numbers which have more than two factors are called composite numbers. The prime numbers formula helps in representing the general form of a prime number.
