# Circumference 9811

Kristýna chose a certain odd natural number divisible by three. Jakub and David then examined triangles with a circumference in millimeters equal to the number selected by Kristýna and whose sides have lengths in millimeters expressed by different integers.
Jakub found a triangle in which the longest side has the longest possible length and wrote this value on the board. David found a triangle in which the shortest side has the longest possible length, and he also wrote this value on the board. Kristýna correctly added both measurements on the board, and she got 1,681 mm.
Determine which number Kristýna chose.
