What is a composite and prime number

A Prime Number can be divided evenly only by 1 or itself.

And it must be a whole number greater than 1.

7 can only be divided evenly by 1 or 7, so it is a prime number. But 6 can be divided evenly by 1, 2, 3 and 6 so it is NOT a prime number (it is a composite number).

Make sense?

Prime numbers are numbers that we can only divide by 1 and it self.

example - 2 can only be divided by 2 and 1

composite numbers are numbers we can divide by two or more numbers

example - 4 can be divided by 1,2 and 4.
