Yes because it has more than two factors

1155 is a composite number because it ends with 5. All numbers that end with 5 except 5 itself are composite numbers because they are divisible by 5, which means there are at least three factors, 1, 5, and the number itself.

Any number ending in 5 (or 0) is divisible by 5 and is therefore composite. The only exception is 5 itself which is prime.
