%N Numbers equal to the carryless sum of their divisors.

%C Equivalently, numbers k such that A323394(k) = k.

%H <a href="/index/Ca#CARRYLESS">Index entries for sequences related to carryless arithmetic</a>

%e For k = 14:

%e - the divisors of 14 are: 1, 2, 7, 14,

%e - the sum of the units are: 1 + 2 + 7 + 4 = 14 == 4 (mod 10),

%e - the sum of the tens are: 1,

%e - hence A323394(14) = 14 and 14 belongs to the sequence.
