%N Numbers m whose decimal representation includes at least one digit that divides every digit of m.

%C Every number that has a digit '1' (cf. A011531) is in this sequence. Sequence A034838 (every digit divides n) is not a subsequence (e.g., 324 is not in the present sequence). - _M. F. Hasler_, Jan 10 2016
