%N A069716 Smallest number such that the LCM of the digits equals n, or 0 if no 
               such number exists.
%F A069716 a(n)=Min{x; Apply[LCM, IntegerDigits[x]]=n}.
%e A069716 n=20: a(20)=45 because LCM[4,5]=20. If one solution exists, then an infinite 
               number of solutions exists. E.g. for n=20 455,445555555,545544 etc. 
               are also solutions.
%t A069716 f[x_] := Apply[LCM, IntegerDigits[x]] t = Table[0, {256} ]; Do[ s = f[n]; 
               If[s < 257 && t[[s]] == 0, t[[s]] = n], {n, 1, 10000} ]; t
