A composite number is a positive integer that has at least one positive divisor other than one or itself, meaning it has more than two distinct positive divisors.
Let's examine the numbers you've provided:
- 27: This number can be divided by 1, 3, 9, and 27, so it is composite.
- 47: This number can only be divided by 1 and 47, so it is not composite; it is a prime number.
- 37: This number can only be divided by 1 and 37, so it is not composite; it is also a prime number.
- 67: This number can only be divided by 1 and 67, so it is not composite; it is a prime number.
In summary, the only composite number from your list is 27.
