A prime number is a whole number greater than 1, whose only two whole-number factors are 1 and itself. Read on at the link.

A prime number is a whole number greater than one which has no divisors except one and itself. A composite number is a whole number greater than one that isn't prime, that is, a product of two or more whole numbers. See http://en.wikipedia.org/wiki/Prime_number

The common definition is a number only divisible by 1 and itself. This has redundancy for 1, and does not apply.

More formally,**The Fundamental Theorem of Arithmetic**
Every positive integer greater than one can be written *uniquely* as a product of primes, with the prime factors in the product written in order of nondecreasing size.

So 1 is left out.

More formally,

So 1 is left out.

A prime numbers is defined as a natural number greater than one that has no positive divisors other than one and itself. Since one obviously is not greater than one, it is not a prime number.

"A **prime number** (or a **prime**) is a natural number greater than 1 that has no positive divisors other than 1 and itself." - wikipedia

A list would be impossible without a limit. if you can't divide it by anything but 1 and the number itself(which would also mean that you were dividing by one), then it's prime.

4 is not prime, because it is divisible by 1, 2, and 4. 5 is prime, because it cannot be divided by anything except 1 and 5(itself).

Prime numbers are those numbers (greater than 1) that cannot be divided by any
number except themselves and one.

The Greek Eratosthenes created a method to find out these prime numbers, although it only worked over a limited range:

1) Write out the numbers from 1 to 100 in ten rows of 10.

2) Cross off number 1, because all primes are greater than 1.

3) Number 2 is a prime, so we can keep it, but we need to cross off the multiples
of 2 (i.e. even numbers).

4) Number 3 is also a prime, so again we keep it and cross off the multiples
of 3.

5) The next number left is 5 (because four has been crossed off), so we keep
it and cross of the multiples of this number.

6) The final number left in the first row is number 7, so cross off its multiples.

7) You have finished. All of the "surviving" numbers (coloured in
white below) on your grid are prime numbers.
