Ten distinct integers are placed on the vertices of a regular decagon satisfying both the following conditions:
• The product of two non adjacent integers on the decagon is a multiple of n.
• The product of any pair of adjacent integers is NOT a multiple of n.

Determine the minimum value of n.

I think it is more than an improvement (5,336,100 << 6,469,693,230). I think it is the answer. :-)
