Question

Which is the number that is neither prime nor composite?

Answer 1

Determine the number that is neither prime nor composite.

A prime number is one with only two factors: one and the number itself. As a result, a prime number has two elements.

A composite number is one with components other than one and the number itself. A composite number is made up of more than two elements.

Since it is divisible only by one, the number that is neither prime nor composite is 1. It just has one component.

Hence, the $1$is neither a prime number nor a composite number.
