title: 'Problem 388: Distinct Lines'
---
## Description
Consider all lattice points (a,b,c) with 0 ≤ a,b,c ≤ N.
From the origin O(0,0,0) all lines are drawn to the other lattice points.
Let D(N) be the number of distinct such lines.
You are given that D(1 000 000) = 831909254469114121.
Find D(1010). Give as your answer the first nine digits followed by the last nine digits.
