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
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.
1 is not considered a prime number; 1 is a perfect square.
Well, yes, the number 1 is usually considered in a special category. It is not considered prime, but it isn't composite, either.

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.
It is one number.

1 is not considered a prime number; 1 is a perfect square.
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.
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.
