Best Answer

48 has factors other than 1 and itself, so it is not a Prime number. It is an even number that is greater than 2, so it also has 2 as a factor. Therefore, it is a composite number. All even numbers greater than 2 are composite numbers.

No number that ends in an '8' can be prime; it is at least divisible by 2. Use this kind of thinking to derive the other factors of 48.
