What is the biggest 5 digit number such that when multiplied by a single digit, the result is a six digit number, with all digits identical?
(In reply to re(2): Solution (spoiler) Base 12 error
Given that base-36 is the largest base where all its digits have a recognized standard notational acceptance [0-9,A-Z] the largest representable five-digit number multiplied by a single digit resulting in a six-digit number is the base-36:
YU0YU * V = UUUUUU.
(YU0YU36 = 6018753010 > 9523810)
