Question 13
For every $m \ge 2,$ let $Q(m)$ be the least positive integer with the following property: For every $n \ge Q(m),$ there is always a perfect cube $k^3$ in the range $n \lt k^3 \le m \cdot n.$ Find the remainder when $$
\sum_{m=2}^{2017} Q(m)
$$ is divided by $1000.$
\sum_{m=2}^{2017} Q(m)
$$ is divided by $1000.$
