Let \( a = 27 \) and \( b = 4 \). Determine several pairs of integers \( q \) and \( r \) so that \( 27 = 4q + r \). For example, if \( q = 2 \) and \( r = 19 \), we obtain \( 4q + 19 = 27 \). The following table is set up for various values of \( q \).

For each \( q \), determine the value of \( r \) so that \( 4q + r = 27 \).

\[
\begin{array}{|c|c|c|c|c|c|c|c|c|c|c|}
\hline
q & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 \\
\hline
r & 23 & 19 & 15 & 11 & 7 & 3 & -1 & -5 & -9 & -13 \\
\hline
4q + r & 27 & 27 & 27 & 27 & 27 & 27 & 27 & 27 & 27 & 27 \\
\hline
\end{array}
\]

What is the smallest positive value for \( r \) that you obtained in your examples? How does it compare to 4?
