%N Largest number m such that n^m divides tau(n), where tau(n)=A000594(n) is Ramanujan's tau function.
%H Eric Weisstein's World of Mathematics, <a href="http://mathworld.wolfram.com/TauFunction.html">Tau Function.</a>
%e tau(2) = -24 and 2^3 divides 24, so a(2) = 3.
%e tau(3) = 252 and 3^2 divides 252, so a(3) = 2.
%e tau(4) = -1472 and 4^3 divides 1472, so a(4) = 3.
