A prime is an integer greater than 1 whose only divisors are 1 and itself.
A prime number is a number which has no factors other than 1 (called non-trivial factors). Thus 13 is prime but 15=3*5 is not prime. A number which is not prime is called composite. A polynomial which has no factors other than 1 is called irreducible.
A number having exactly two factors, 1 and itself. For example: 2, 3, 5, 7, 11 are prime numbers.
A number whose only factors are itself and 1.
a number that has no factor but itself and 1
of or relating to or being an integer that cannot be factored into other integers; "prime number"
an integer only divisible by itself and by one
an integer with exactly two positive divisors
a number that can only be divided by one and itself
a number that has only two factors, itself and the number one
a number that is divisible by itself and one
a number that relates only to itself and to one
a positive integer with exactly two factors
a whole number that cannot be divided (without remainder) by any numbers except itself and one
An integer greater than one whose only positive factors are 1 and itself. (2, 3, 5, 7, 11, 13, 17, and 19 are prime numbers.)
a polynomial that does not factor.
A natural number greater than 1 is prime if and only if the only positive integer factors of are 1 and The first seven primes are 2, 3, 5, 7, 11, 13, 17.
