Problem
What is the maximum value of 
for which there is a set of distinct positive integers 
for which
![\[k^2_1 + k^2_2 + ... + k^2_n = 2002?\]](http://latex.artofproblemsolving.com/7/d/a/7da913f9b8644e18078f96cf0ab0c4e928633633.png)
Solution
If 
, then 
. Since 
, 
must be 
to some factor of 6. Thus, there are four (3, 9, 27, 729) possible values of 
.
