Modern Puzzles by Henry Ernest Dudeney: $67$
- A Digital Difficulty
- Arrange the $10$ digits, $1 \ 2 \ 3 \ 4 \ 5 \ 6 \ 7 \ 8 \ 9 \ 0$, in such order that they shall form a number
- that may be divided by every number from $2$ to $18$ without in any case a remainder.
- As an example, if I arrange them thus, $1 \ 2 \ 7 \ 4 \ 9 \ 5 \ 3 \ 6 \ 8 \ 0$, this number can be divided by $2$, $3$, $4$, $5$ and so on up to $16$, without any remainder,
- but it breaks down at $17$.
