Hello Hong, Dung and Trung,

	Thank you all for your effort in solving the problem. 
Geez! you are all smart girl and guys! Re: the problem is 
that finding a seven-unique-digit number, which is divisible 
by every digit in it, except zero, of course! Under this 
condition, I think your solution of 9867312 is correct. I 
guess the credit has to go to Thanh Hong first for her 
initial working out, followed by Dung and Trung. 

	Here is another problem for you: Find the smallest 
integer number N, so that N! is divisible by 7^100 [e.g. 7 to 
the power of 100].

	Thank you for your help and good luck with your study.
