A composite number is a positive integer that has at least one positive divisor other than one and itself, meaning it can be divided evenly by numbers other than just 1 and itself.
Let's evaluate the options provided:
- 47: This is a prime number (it has no divisors other than 1 and 47).
- 37: This is also a prime number (it has no divisors other than 1 and 37).
- 67: This is another prime number (it has no divisors other than 1 and 67).
- 27: This is a composite number (it can be divided evenly by 1, 3, 9, and 27).
Therefore, the number classified as composite is 27.
