%N Numerators of n divided by the product of the anti-divisors of n.
%C See A066272 for definition of anti-divisor.
%F a(n) = n/GCD(n, A091507(n)) = n/A093394(n)
%e The anti-divisors of 18 are 4, 5, 7, 12. Hence a(18) = 18/GCD(4*5*7*12, 18) = 3.
%Y Cf. A066417, A091507, A093394, A093396 (denominators).
