$27$ is a composite number

#### Explanation:

To determine whether a number is prime or composite, we need to look to see if that number has any factors other than 1 and itself.

A prime number is defined as an integer greater than 1 that can only be divided by the number $1$ and itself.

A composite number can be broken down into prime numbers.

As we look to see if there is anything that multiplies to $27$, we find that $3$ and $9$, therefore $27$ can not be prime.
