There are two types of integers (positive and negative whole numbers): prime and composite.
Firstly 0 and 1 are neither prime nor composite.
Prime numbers are numbers that cannot be divided by any other whole number (except for of course itself and 1). Some examples of primes are 2, 13, 29. No number goes into these. In some texts, (particularly abstract algebra books) they allow negative numbers to be prime. So -2, -13, and -29 would also be prime.
Composite numbers are every other whole number, such as 4, 9, 100. These all can be divided by a smaller number.
Zero and one aren't prime or composite because they're special in the sense that anything multiplied by one is itself and anything multiplied by zero is zero.

A prime number (or prime integer, often simply called a "prime" for short) is a positive integer that has no positive integer divisors other than 1 and itself. (More concisely, a prime number is a positive integer having exactly one positive divisor other than 1.) For example, the only divisors of 13 are 1 and 13, making 13 a prime number, while the number 24 has divisors 1, 2, 3, 4, 6, 8, 12, and 24 (corresponding to the factorization ), making 24 not a prime number. Positive integers other than 1 which are not prime are called composite numbers.
Prime numbers are therefore numbers that cannot be factored or, more precisely, are numbers whose divisors are trivial and given by exactly 1 and the number itself.
The first few primes are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37...

prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, and 113.
they could not be devided into other numbers exept for itself which will be 1 or vice versa.

An integer greater than 1 is prime if it can't be divided, and leave a remainder of zero, by any number other than 1 or itself.
2, 3, 5, 7, 11, 13, 17, 19, 23, ...
4 can be divided by 2 and leave 2
6 can be divided by 3 and leave 2
etc.

Edit: 1 IS NOT PRIME

Prime numbers are numbers that can only be wholly divided by 1 and themselves.
Examples include:
1, 3, 5, 7, 11, 13, 17, 19, 23, et cetera...

A prime number has no factors other than itself and 1.
Note that 1 is NOT considered a prime number.
Also, 2 is the only even prime number
