225 is composite. The last digit is 5, so it is divisible by 5. Therefore it is composite. In fact, it is 15 squared. In contrast, a Prime number is a number that is divisible only by 1 and itself; it has no other factors. The factors of 225 are 1, 3, 5, 9, 15, 25, 45, 75, and 225. Therefore, 225 is a composite number.
