What is a prime?

Definition of prime 1

An integer greater than i is called a prime number if its only positive divisors (factors) are one and itself. For example, the simply divisors of 11 are 1 and 11, and so 11 is a prime number number, while the number 51 has divisors 3, 17 and 51 itself (51 = iii•17), making 51 not a prime.

Definition of prime 2

A positive integer that is not divisible without residuum past whatever integer except itself and one, with i often excluded.

Note that:

0 (naught) is non a prime number because information technology isn't divided by itself. Goose egg has an space number of divisors (any nonzero whole number divides zero). It cannot be written as a product of ii factors, neither of which is itself, so zero is likewise not composite. More than concisely, zero is non a prime or a composite number either.
1 (i) is neither a prime nor a composite number. One has only one positive divisor. It cannot be written as a product of two factors, neither of which is itself, then one is also not composite. THe number ane falls in a class of numbers called units.
