# Divisibility from 1 to 9

**Number Theory**Level 4

Arrange the digits from 1 to 9 in such an order that the first two digits form a number that is a multiple of 2, the first three digits form a number that is a multiple of 3, and so on.

Example: 123456789 doesn't work, because 12 is divisible by 2 and 123 is divisible by 3, but 1234 isn't divisible by 4.
