Definition of prime 1
An integer greater than one is called a prime number if its only positive divisors (factors) are one and itself. For example, the only divisors of 11 are 1 and 11, so 11 is a prime number, while the number 51 has divisors 3, 17 and 51 itself (51 = 3•17), making 51 not a prime number.
Definition of prime 2
A positive integer that is not divisible without remainder by any integer except itself and 1, with 1 often excluded.
