Zero is not considered a Prime number because it does not have any factors other than itself, which is a prerequisite for a number to be considered prime. Additionally, zero is not considered a composite number because it does not have more than one factor, which is another requirement for a number to be classified as composite. Zero is a special case and is treated as its own separate category.

What whole number are neither prime or composite?

One is neither a prime nor a composite number. A prime number is one with exactly two positive divisors, itself and one. One has only one positive divisor which is itself so it is not prime. Furthermore, it cannot be written as a product of two factors, neither of which is itself. This tells us that one is also not composite. The other number which is neither prime not composite is Zero which has an infinite number of divisors since any nonzero whole number divides zero. Zero cannot be be written as a product of two factors, neither of which is itself, so zero is also not composite.
