❖ A composite number is 27. 27 is composite because there are more numbers than 1 and itself that can be multiplied to create 27. The two other numbers to make 27 are 3 x 9. All the other answer choices are prime numbers because no other numbers besides 1 and itself can be multiplied to make that number.
