%N Numbers n such that the list of divisors of n contains 5 distinct digits (in base 10).

%C Numbers n such that A037278(n), A176558(n) and A243360(n) contain 5 distinct digits.

%H David A. Corneth, <a href="/A243538/b243538.txt">Table of n, a(n) for n = 1..10000</a>

%e 45 is in sequence because the list of divisors of 45: (1, 3, 5, 9, 15, 45) contains 5 distinct digits (1, 3, 4, 5, 9).

%o (Excel) [Row n = 1...10000; Column A: A(n) = A095048(n); Column B: B(n) = IF(A(n)=5;A(n)); Arrangement of column B]

%Y Cf. A095048, A037278, A176558, A243360.

%Y Sequences of numbers n such that the list of divisors of n contains k distinct digits for 1 <= k <= 10: k = 1: A243534; k = 2: A243535; k = 3: A243536; k = 4: A243537; k = 5: A243538; k = 6: A243539; k = 7: A243540; k = 8: A243541; k = 9: A243542; k = 10: A095050.

%Y Cf. A243543 (the smallest number m whose list of divisors contains n distinct digits).
