Hello, Jenny!

Find the smallest multiple of 17 that has only 1's in its decimal expansion.

Hint: the numbers in question are of the form (10^n - 1)/9

I haven't found a way to use that hint.

If you're desperate, here's a **very** primitive method.

Divide 17 into a "string of 1's" ... and wait for it to *come out even*. Code:

6 5 3 5 9 4 7 7 1 2 4 1 8 3
---------------------------------
1 7 ) 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
--------------------------------
0

Therefore: 1,111,111,111,111,111 is the smallest multiple of 17.
