A composite number is a positive integer that has at least one positive divisor other than one and itself. In other words, it is a number that can be formed by multiplying two smaller natural numbers.
Let's evaluate the options:
- 37: Prime (only divisible by 1 and 37)
- 67: Prime (only divisible by 1 and 67)
- 27: Composite (divisible by 1, 3, 9, and 27; can be expressed as 3 x 9)
- 47: Prime (only divisible by 1 and 47)
The composite number from the provided options is 27.
