4. If $n$ is the smallest number with the given property, $n$ must have as few digits as possible....3p $2016=9 \cdot 224=\underbrace{9+9+\cdots+9}_{\text {of } 224 \text { times } 9}$ $2 \mathrm{p}$

$$
\text { The number sought is } \quad \begin{gathered}
n=\underbrace{999 \ldots 9}_{\text {of } 224 \text { times } 9}
\end{gathered}
