Which of the following is a composite number?

Explanation:
Composite numbers are integers greater than 1 that can be written as a product of two integers both greater than 1. The given number can be factored in such a way, so it has more than two positive divisors. That makes it composite. The other numbers in the list cannot be factored nontrivially into smaller integers; they have exactly two divisors—1 and themselves—so they are prime.
