A prime number is a number that can only be divided by 1 or itself. A composite number is a number which can be divided by a number other than itself or 1 and not leave a remainder. 178 divided by 2, for example, equals 89 (89 + 89 = 178). Since 2 is not dividing 178 by 1 or by itself and leaves no remainder, it is a composite number.
