A084906 Numbers with at least one place in their decimal representation to insert a division operator such that an integer results. 4

%I

%S 11,21,22,31,33,41,42,44,51,55,61,62,63,66,71,77,81,82,84,88,91,93,99,

%T 101,102,105,111,121,122,123,124,126,131,141,142,147,151,153,155,161,

%U 162,164,168,171,181,182,183,186,189,191,201,202,204,205,211,213

%N Numbers with at least one place in their decimal representation to insert a division operator such that an integer results.

%C A084904(a(n))>0; for all m=a(n) exists at least one k such that (m mod 10^k)>0 and ((m/10^k) mod (m mod 10^k))=0.

%e 364->36/4=9 therefore 364 is a term; 365 is not a term, as 3/65 and 36/5 are not integers.

%Y Cf. A084905.

%K nonn,base

%O 1,1
