<span>trick question One is neither a prime nor a composite number. A prime number is divisible by its self and one. One has only one
positive divisor. It cannot be written as a product of two factors,
neither of which is itself, so one is also not composite. It falls
in a class of numbers called units. These are the numbers whose
reciprocals are also whole numbers.</span>
1 is neither because it can't be divided evenly only by 1, or itself and it can't <span>be divided evenly by numbers other than 1 or itself.</span><span>
