COMMENTS

See A066272 for definition of anti-divisor.

LINKS

Table of n, a(n) for n=3..52.

FORMULA

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

EXAMPLE

The anti-divisors of 18 are 4, 5, 7, 12. Hence a(18) = 4*5*7*12/GCD(4*5*7*12, 18) = 280.

CROSSREFS

Cf. A066417, A091507, A093394, A093395 (numerators).
