Need Answer to the Following Please:
Using the 9 digits, 1, 2, 3, 4, 5, 6,7, 8 and 9 you can arrange four different digits to form a fourdigit number that is NOT divisible by 7. The digits 1238 cannot be arranged to create a fourdigit number that is divisible by 7. The digits 1389 also cannot be arranged to form a fourdigit number that is divisible by 7. Find one additional set (not 1238 or 1389) of four different digits that is not divisible by 7. Provide the digits to form the smallest four digit value.
Will you Please explain the answer also. Thank You

what's to explain? The number is not divisible by 7.
How about 6789 or 5678 or 1579?

Oops. I see I did not read carefully; no arrangement is allowed to be divisible by 7. In that case, the only one I can find is
2469
