You get the lines because you're lining up all numbers divisible by 2, 3, 5 and 7. You get a very similar pattern with 210, and a sparser one with, for example, 30030.

Yes, that's right. I wonder if it's a similar thing showing up in the spiral. Just a simple consequence like the one that causes the lines.
