Only positive integers can be either prime numbers or composite numbers or neither; therefore, of the set of positive integers, only the number one (1) is neither a prime number nor a composite number. A prime number is a positive integer that is exactly divisible, i.e., a zero remainder, by exactly two positive integers: itself and 1. For example, 5 and 7 are prime numbers because each is exactly divisible by only two positive integers: itself and 1, i.e., 5/5 = 1 & 5/1 = 5 and 7/7 = 1 & 7/1 = 7. The prime numbers less than 30 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29..

By the definition of what a prime number is, one (1) is NOT a prime number because it is exactly divisible by only ONE positive integer --- just itself, thus 1 does not fulfill the necessary "exactly TWO-positive integers" requirement in order to be prime. On the other hand, Composite numbers are positive integers that are exactly divisible, i.e., a zero remainder, by other positive integers besides just itself and 1, for example, 6 is a composite number because it is a positive integer that is exactly divisible by not only itself and 1, but also by 2 and 3: 6/6 = 1, 6/1 = 6, 6/3 = 2, and 6/2 = 3. .

Therefore, one (1) is not a composite number because it is exactly divisible by just itself and no other positive integers, thus 1 does not fulfill the necessary "exactly divisible by other positive integers besides just itself and 1" requirement in order to be composite. .

.Therefore, the number one (1) is neither a prime number nor a composite number.
