COMMENTS

See A066272 for definition of anti-divisor.

LINKS

Table of n, a(n) for n=3..76.

FORMULA

a(n) = n/GCD(n, A091507(n)) = n/A093394(n)

EXAMPLE

The anti-divisors of 18 are 4, 5, 7, 12. Hence a(18) = 18/GCD(4*5*7*12, 18) = 3.

CROSSREFS

Cf. A066417, A091507, A093394, A093396 (denominators).

Sequence in context: A271726 A123901 A214682 * A176774 A126352 A094758
