I think the answer has to be **non-prime number**. This would mean that it is either 14 letters or that the dash takes up a space. This would also mean that you made a mistake in your placement of question marks.

Ingenious, cburr, but no cigar! The answer is **composite number**.

A 15-letter word meaning "A whole number that has more than 2 factors" is a composite number.

A whole number that has more than 2 factors is called a composite number. For example, 16 is composite because it has five factors (1, 2, 4, 8, and 16).

Do not confuse composite number with prime number. Prime number has exactly two factors 1 and itself. For example: 19 is prime, since 1 and 19 are the only two factors that will go into it evenly.
