Think to yourself - can this number be divided by any other number and have an answer that does not have any remainder or fraction left over.
27 cannot be divided by any other number without having 'left overs.'
28 can be divided by 7 or 4 without 'left overs.' 28 divided by 7 is 4, etc.

Another answer:

They are both composite because each of them has more than two factors

Factors of 27 are 1 3 9 27
