Prime numbers are numbers that is only divisable by 1 and itself. Prime numbers are normally odd numbers but not all odd numbers are prime numbers except for 2, which is an even number. eg:
9 is an odd number but it is NOT a prime number because it can be divived by the prime number 3.
Hope that helps...

numbers that don't have factors other than itself and one.
For example;
3 is a prime number because it's only factors are 1 and 3
7 is a prime number because it's only factors are 1 and 7

A prime number is a whole number that can only be divided evenly by two whole numbers.
For example, 2 is a prime number because it is a whole number and it can be divided by only 1 and 2 evenly. You divide it by 1 you get two, you divide it by 2 you get one.
Three is also prime, because it is a whole number and you can only divide it by 1 and 3 evenly. Divided by 1 it's 3, and divided by 3 it's 1.
So, a prime number could also be called a whole number that can only be divided by itself and one.
There you go. I'm glad I could help. :)

basically a prime number can't get any smaller division wise. for example 1, 3, 5, 7 see? 9 is next in the odd numbers but it won't work...it is divisible by 3 3 times 3 equalls 9

1 IS NOT a prime number. 1 only has one factor, namely 1.
Prime numbers have exactly two factors, 1 and themselves.
It's just a definitional issue, but getting it wrong can cost you points on a tricky exam question.
