%N Numbers that are divisible by each of their digits but that are not divisible by the sum of their digits or by the product of their digits.
%C Numbers which are divisible by the sum and the product of their digits (A038186) are also divisible by each of their digits (A034838)
%C The product of the digits of n are trivially divisible by each digit; so if that product divides n, each digit must divide n. - _Franklin T. Adams-Watters_, Jul 02 2017

%e 15 is divisible by its digits 1 and 5, and 15 is divisible by the product of its digits 1*5 = 5, but 15 is not divisible by the sum of its digits 1+5 = 6, hence 15 is a term.
%e 48 is divisible by its digits 4 and 8, and 48 is divisible by the sum of its digits 4+8 = 12, but 48 is not divisible by the product of its digits 4*8 = 32, hence 48 is a term.
%e 124 is divisible by its digits 1, 2 and 4, but 124 is not divisible by the product of its digits 1*2*4 = 8 and 124 is not divisible by the sum of its digits 1+2+4 = 7, hence 124 is a term.
%e 24 is divisible by its digits 2 and 4, and 24 is divisible by the sum of its digits 2+4 = 6, and 24 is also divisible by the product of its digits 2*4 = 8, hence 24 is NOT a term.
