Composite
Answered by GPT-4o mini
A composite number is a positive integer that has at least one positive divisor other than one and itself. In other words, a composite number has more than two distinct positive divisors.

Let's analyze the numbers you provided:

- **37**: This number is prime as it has only two divisors (1 and 37).
- **27**: This number is composite because it can be factored into \(3 \times 9\) (or \(3 \times 3 \times 3\)), so it has divisors other than 1 and 27.
- **47**: This number is prime as it has only two divisors (1 and 47).
- **67**: This number is prime as it has only two divisors (1 and 67).

Thus, among the numbers listed, **27** is classified as a composite number.

Zero is classified as **neither prime nor composite**.

The reason is that:

- A prime number is defined as a natural number greater than 1 that has exactly two distinct positive divisors: 1 and itself.
- A composite number is defined as a natural number greater than 1 that has more than two positive divisors.

Since zero does not meet the criteria for being either prime or composite, it is classified as neither.
