Factors of the first 1,000,000 integer numbers

A quick Google search only brought up lists up to e.g. 1,000, so here’s a CSV with the factors for the first 1,000,000 integers. (Note that from a programming perspective, you’re most likely better off calculating the factors yourself rather than parsing a CSV file. So it’s not quite clear if this list is actually useful.) Feel free to do with it whatever you want.
