1,1

Also numbers n such that smallest digit of concatenation of all divisors of n (A037278 or A176558) is 0.

Sequence is not the same as A011540, first deviation is at a(41): A011540(41) = 220, a(41) = 214.

Complement of 209931.

Table of n, a(n) for n=1..54.

Number 214 is in sequence because smallest digit of all divisors of 214 (1, 2, 107, 214) is 0.

Cf. A209929 (smallest digit of all divisors of n).

Sequence in context: A044895 A156819 A139079 * A011540 A098394 A057169

Adjacent sequences: A209929 A209930 A209931 * A209933 A209934 A209935
