225 is a composite number. This is because composite numbers are any number that has more than two factors (one and itself). Therefore, since there are many factors of 225 besides one and itself such as 3, 5, and 9, that makes it a composite number.
A composite number is a positive integer which has a positive divisor other than one or itself. In other words, if 0 < n is an integer and there are integers 1 < a, b < n such that n = a × b then n is composite. By definition, every integer greater than one is either a prime number or a composite number. The number one is a unit - it is neither prime nor composite. For example, the integer 14 is a composite number because it can be factored as 2 × 7.
