Between 2200 and 2600 guests were invited to the Mayor's luncheon. The organizer decided to arrange the seating so that each table would accommodate an equal number of guests, and the number of guests at each table would be an odd number.

The organizer determined that the following arrangements would not work:
3 guests per table (2 would be left without seating); 5 guests per table (4 left out); 7 guests per table (6 left out); and 9 guests per table (8 left out).

However, when he tried seating 11 guests per table, no guests were left without a place to sit.

How many guests in total were invited to the luncheon?
