%N A276465 Divisors of 16450.
%C A276465 Conjecture: 16450 is the only number such that Sum_{d | n} 0.d is an integer, where 0.d means the decimal fraction of divisors d of n obtained by writing d after the decimal point:
%C A276465 0.1 + 0.2 + 0.5 + 0.7 + 0.10 + 0.14 + 0.25 + 0.35 + 0.47 + 0.50 + 0.70 + 0.94 + 0.175 + 0.235 + 0.329 + 0.350 + 0.470 + 0.658 + 0.1175 + 0.1645 + 0.2350 + 0.3290 + 0.8225 + 0.16450 = 9.
%C A276465 There are no other numbers with this property <= 5*10^7.
%F A276465 A276467(16450) = 1.
