2 is a whole number. For example the only divisors of 13 are 1 and 13 making 13 a prime number while. For a number to be classified as a prime number it should have exactly two factors.

If the prime factorisation results in the product of two or more prime numbers then it is a composite number. The number 4 is not prime since it has three divisors 1 2 and 4 and 6 is not prime since it has four divisors 1 2 3 and 6. The prime factorization of 20 2 2 5 The number 20 is not a prime number because it is possible to factorize it.
