It is composite because it isn't prime.

Hope this helps.

Answer 2

The number 86 is not a composite number because it cannot be divided evenly by any other number except for 1 and itself. A composite number is defined as a positive integer greater than 1 that has at least one divisor other than 1 and itself.
