Digits 1-9 (Posted on 2002-06-05)

Can you arrange the digits 1-9 in any order so that:

The number formed by the first two digits is divisible by 2.

The number formed by the first three digits is divisible by 3.

The number formed by the first four digits is divisible by 4

and so on up to nine digits...

This leaves us with only ten possibilities to test out by actually dividing the first seven digits by 7, a vast improvement over Nick's 48
