FORMULA

a(n) ~ n. - Charles R Greathouse IV, Jul 22 2011

EXAMPLE

35 is included because 5 is a divisor of 35, but 37 is not included because neither 3 nor 7 is a divisor of 37.

MATHEMATICA

PROG

(Haskell)

a038770 n = a038770_list !! (n-1)

a038770_list = filter f [1..] where

   f u = g u where

     g v = v > 0 && (((d == 0 || r > 0) && g v') || r == 0)

           where (v', d) = divMod v 10; r = mod u d
