Expert Answer:

Yes, it's correct.

A composite number is a positive integer which has a positive divisor other than one or itself. In other words, if n > 0 is an integer and there are integers 1 < a, b < n such that n = a × b then n is composite.

Since the given number has a divisor 13 or 78, apart from 1 and the number itself, it's composite.
