We have \(7(a - 1) = 17(b - 1)\).

This can be written as:

\(7(a - 1) = 17(b - 1)\)
\(7 \times 17 = 17 \times 7\). This is the minimum possible value.

So \((a - 1)=17\) and \((b - 1)=7\)

It could also be:

\(7(a - 1) = 17(b - 1)\)
\(7 \times 34 = 17 \times 14\) which is \(7 \times 17 \times 2 = 17 \times 7 \times 2\).

This is \((a - 1)=34\) and \((b - 1)=14\) also possible but not the minimum possible value.
