It cannot be 123456789 because 1234 is not divisible by four.......ok !
I'll tell more clearly......if the no.s are 123456789 then 1 should be divisible by one.......12 should be divisible by 2 .......123 should be divisible by three......1234 should be divisible by 4.......12345 should be divisible by 5 and so on....but 1234 is not divisible by 4 so 123456789 is not the answer....

123456789?
1 is divisible by 1.
2 is divisble by 2.
and so on.
You can always have different versions of this, and have some numbers, e.g. 2, as 4, which is also divisible by 2. But the number should still be one digit. On second thought, that won't work. Because you will repeat numbers, like when you put in the 4, there will be 2 fours. So, the number MUST be 123456789! :)
