3. (3 points) Let $x_{1}, x_{2}, \ldots, x_{200}$ be natural numbers greater than 2 (not necessarily distinct). In a $200 \times 200$ table, the numbers are arranged as follows: at the intersection of the $i$-th row and the $k$-th column, the number $\log _{x_{k}} \frac{x_{i}}{9}$ is written. Find the smallest possible value of the sum of all numbers in the table.
