%N First n-fold perfect number divided by 30240, or 0 if the quotient is not an integer.

%C The first n-fold perfect numbers are A007539(n) = 1, 6, 120, 30240, 14182439040, ..., for n = 1, 2, 3, 4, 5, ...

%H T. D. Noe, <a href="/A227767/b227767.txt">Table of n, a(n) for n = 1..8</a>

%F a(n) = A007539(n)/30240 if 4 <= n <= 8.

%e The first 5-fold perfect number is A007539(5) = 14182439040, so a(5) = 14182439040/30240 = 468996.

%Y Cf. A007539, A227765, A227766, A227768, A227769.
