A composite number is a positive integer that has at least one positive divisor other than one and itself, meaning it can be divided by numbers other than 1 and itself.
Let's analyze the numbers given:
- A) 27: This number is composite because it can be factored into \(3 \times 3 \times 3\) (or \(3^3\)).
- B) 47: This number is prime because it has no divisors other than 1 and 47.
- C) 37: This number is also prime because it has no divisors other than 1 and 37.
- D) 67: This number is prime as well because it has no divisors other than 1 and 67.
The only composite number from the options provided is A) 27.
