Diophantine reciprocals II
Problem 110Published on Friday, 2nd December 2005, 06:00 pm; Solved by 3919
In the following equation x, y, and n are positive integers.
It can be verified that when n = 1260 there are 113 distinct solutions and this is the least value of n for which the total number of distinct solutions exceeds one hundred.
What is the least value of n for which the number of distinct solutions exceeds four million?
NOTE: This problem is a much more difficult version of problem 108 and as it is well beyond the limitations of a brute force approach it requires a clever implementation.
