any integer that cannot be divided by another number evenly except by itself and 1; two is the smallest prime number Example: "2, 3, 5, 7, 11, 13"

A whole number greater than 1 that can be divided exactly (i.e., with no remainder) only by itself and 1. The first few primes are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37.

a prime number has exactly two factors, itself and 1. Examples: 2 (factors 2, 1), 3 (factors 3, 1); 51 is not prime (factors 51, 17, 3, 1), and 1 itself is not considered a prime number.

an integer that has no integral factors but itself and 1

a counting number that only has two factors--itself and one

a natural number with exactly two divisors

an integer greater than one which can be divided only by one and itself

an integer greater than one which is not a product of two smaller positive integers

an integer that has exactly two factors

an integer whose value is greater than one and can be divided by only two integers (one and the value itself)

a number greater than one that cannot be divided by any number but itself and, um

a numbers greater than one whose factors are only one and itself

a number that cannot be divided by any other number, except itself and one

a number that cannot be expressed as a product of numbers smaller than the number itself

a number that can only be derived by a factor of one and itself

a number that can only be divided by one or by itself

a number that is not divisible, without remainder, by any number except itself and unity (the number one)

a number that ONLY divides by itself and one

a number which cannot be divided by any number excect and itself

a number which cannot be made by multiplying any other numbers together

a number which can only be divided by one and itself

a number which has no factors apart from itself and one

a number whose only positive factors

a number whose sole divisors are one and itself

a number with exactly two factors

a number with special properties

a positive integer divisible by no integers other than unity and itself

a positive integer that has exactly two

a positive integer that is evenly divisible by only two numbers--one and itself

a positive number

a whole number greater than one, divisible without remainder only by itself and one

a whole number that cannot be divided

a whole number that is divisible by itself and one

a whole number which cannot be EXACTLY divided by a smaller whole number

A whole number greater than 1 that can only be divided evenly by itself and 1 (e.g., 17).

an integer whose only factors are 1 and itself

A natural number not equal to 1 whose only natural number factors are itself and 1.

a whole number greater than 1 having exactly two whole number factors, itself and one.  For example, 7 is prime since its only whole number factors are 1 and 7.

A prime number is a natural number that has only one and itself as factors. Examples: 2, 3, 5, 7, 11, 13, 17, 19, 23, … are prime numbers.

A counting number (integer) that can only be evenly divided by 1 and the number itself. The first ten prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 29, and 29.

An integer greater than 1 with no positive integer divisors other than 1 and itself; e.g., 2, 3, 5, 7, 11, 13, 17, and 19 are prime numbers.

A whole number, greater than 1, that has exactly two factors: itself and 1.

any whole number with only two factors, 1 and itself (e.g., 2, 3, 5, 7, 11, etc.).

whole number greater than 0 that has exactly two different factors, 1 and itself. 5 is a prime number because its only factors are 1 and 5.

A natural number that can be evenly divided only by itself and 1.

A whole number (integer greater than zero) which is divisible only by one and itself. Small prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, .... Mathematically, there are an infinite number of prime numbers, which are distributed fairly uniformly among the integers. There are robust methods for discovering prime numbers of any size.

A number that can be divided by only itself and one. probability: The numerical measure of the chance of an outcome or event occurring.

A number that has only two factors, 1 and itself.

A number that has exactly two factors, 1 and the number itself.

A whole number, greater than 1, that has exactly two factors, 1 and itself.

A number that is only divisible by 1 and itself.

Any integer greater than 1 that is divisible only by 1 and itself.
