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 analyze the numbers given:
- 67: Prime (only divisible by 1 and 67).
- 47: Prime (only divisible by 1 and 47).
- 27: Composite (divisible by 1, 3, 9, 27).
- 37: Prime (only divisible by 1 and 37).
The composite number among the options is 27.
