 OFFSET 0,2 COMMENTS 1 is a primitive Niven number, not ending with 0, so a(0)=1. a(n) is the smallest term of A358255 that ends with n zeros for n > 0. LINKS Giovanni Resta, Harshad numbers. FORMULA a(n) = A051885(2^n)*10^n for n > 3. - Rémy Sigrist, Nov 05 2022 EXAMPLE 1300 is divisible by 1+3=4, but 13 and 130 are not divisible by 4; 1300 is the smallest such integer ending with two 0's, so a(2) = 1300.
