Are you sure you've stated the question correctly? 13 is not a divisor of (15! + 3), nor is any number 2-15 except for 3.

From whence did you get this question?
I tutor GMAT/GRE level mathematics privately in the Los Angeles region, as well as via Skype for a discounted rate. Send me a message if you're interested.
