A prime number is any whole integer that is only divisible by 1 and itself. If you try to divide it by any other integer, you will not end up with a whole number (a number without a decimal).
-
A prime number is a whole number greater than one that has exactly two unique factors, one and itself.
-
A prime number is an integer greater than 1 whose only positive factors are itself and 1. EDIT: But is -3 prime? It depends on context. A prime can also be defined as an element of an integral domain not zero or a unit such that if it divides equally into a product, it always divides equally into one or both of the factors. This makes the negatives of prime numbers prime too. However, in many contexts it is taken for granted that only positive primes are being considered - (e.g. in the fundamental theorem of arithmetic, that every integer greater than one can be decomposed into a product of a set of oone or more primes, and that set is always the same set)

A prime number is a whole number that can only be divided by itself and 1 to make another whole number. I was tought that 1 was a prime number because it can only be divided by itself and 1 (which just happen to be the same numbers:)
-
Note that all primes greater than 3 are of the form 6n +/- 1, where n is a positive integer.
-
A number that is only divisible by one and itself

Is 2 a prime number?
-
A prime number is a number that suffers from indivisibility (note that this is the only word I know of that has the same vowel 6 times and no other vowel) by any other whole number beyond itself and one. Examples are: 2, 3, 5, 7, 11, 13, 17, 19 and so on...

I believe 2 is the only even prime number.
