It is neither because 1 has only one factor and that is itself.

Technically 1 is not a Prime number, since the actual definition of prime is having exactly two factors: 1 and itself. 1 is neither a prime number nor a composite number, since it is the only number with only one factor. It is unity.

It is not a prime number because 1 only has one factor, 1.

Some people say it is a composite and some people say it is a prime.

But, according to what my math teacher says, its not!! Yeah, so it is "unique"; it has its "own space".

Neither

It's neither, it has one factor,1. primes have 2 factors.

1 and 0 are the only acceptions to prime and composite.

Neither. primes have only two divisible numbers: 1 and itself. Composites have more than that. take 4 for example. it has 1, 2, and 4 because 2x2=4. Then why is 1 not a prime. It has be be two DIFFERENT numbers, not just 1 and 1.

1 is neither a prime number nor a composite number. Its only factor is itself whereas every prime number has two factors: 1 and itself.

ok well i am in prime and composite in math class and this is how: If the number is a prime then it can only have 2 factors. If it has 3 or more it is a composite number. Say 25 has a lot of factors so it is a composite number. And if 1 has only 1 factor then it is a prime number. And there you have prime and composite.
