I wrote program and could check only small values, and didn't get anyhing useful from it, because too many states required for solving and it takes exponential time.

It seems that I understand idea but not details, may be you know worst case example? Jun27 comment What's the most efficient way to put all the stones in one pile? I dont understand how you've counted number of positions. E.g. you have piles {2,1,1} and make {2, 2, 0}. Your assumption doesnt work, because gcd is two. AFAIU you've not counted this state or p became less by one.

Feb5 comment determine the interval in which the solution is defined maybe you wanted to type $\ln(1)=0$
