The concept of prime or composite is defined only for integers greater than 1.
An alternative argument that is that a 1 has only 1 factor, which is 1. Primes have exactly 2, and composites more than 2. So 1 is neither prime nor composite.
This ensures that the unique prime factorisation theorem (the fundamental theorem of arithmetic) is true.

∙ 12y ago1 is not a Prime number many people consider it to be one but to be a prime number it must only be divisible by 1 and itself. 1 is only divisible by one and nothing else. the number 1 is also not a composite. Composite numbers are divisible by 1, itself and another number which one is not. Instead it falls under a category called a unit

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.
