(By mathematical convention, 1 is the only positive integer considered neither prime nor composite.)If you verify for yourself why each number from 2 to 30 is prime or composite, it will help you remember this list. The number 1 is a unit - "unity" - it is neither prime nor composite. It is a matter of definition. It looks as if 1 should be a prime because 1 is only divisible by 1 and itself, but a prime is defined to be a number with exactly two factors - 1 and itself - but 1 has only one factor. Theres a really good reason why the definition of "prime number" excludes 1. Lets say I ask you to give me the prime factorization of a number.As you can see, 1 doesnt satisfies the basic Definition of prime and composite number. Hence 1 is neither prime nor composite. 0 is not prime or composite because the definition of prime or composite only applies to natural numbers (positive whole numbers which are greater than zero). But why 1 is neither prime nor composite?
