13 guests  in the party can be divided inti 2 groups of 8and5 in 13c8 or 13c5.
The first group of 8 guests can be arranged  around  at one table in 7! ways.
The second group of 5 guests can be arranged  around  at one table in 4! ways.
So,
The number of arrangements is,
=(13!/5!8!)*(4!)*(7!)
=13!/40 is the answer.
