because its not prime or composite
I will assume you mean "positive integers". In this case, the only number that is considered neither prime nor composite is the number 1. 1 has the special role of the identity element of multiplication, meaning that if you multiply a number by 1, it remains unchanged.
it is the first number
Multiplicative identity. Because for any number a, 1*a = a
1 is not considered a prime number; 1 is a perfect square.
the number 1 is a special number. The number 1 is a confusing number to deal with, but it is called a special number.Example: Is 1 prime or composite? It is neither.
Well, yes, the number 1 is usually considered in a special category. It is not considered prime, but it isn't composite, either.

The number 1 is considered a single number.

A composite number is a number that has smaller factors (excluding 1). A prime number is one that doesn't (1 is not considered prime nor composite, because of its special role in multiplication).Since 15 is divisible by 3, it is composite.
1 is the first positive number on the number line.
1 is the smallest natural number. 1 is the factor of every number. 1 is neither prime nor composite.
Square numbers have an odd number of factors, all others have an even number. In this context, primes can either be considered as having 0 factors (an even number) or 2 factors - 1 and itself, again, an even number.
