I was not happy not really understanding the factor part of the solution to part2 of #adventofcode #day11 so I did some reading and some experimenting.

This PDF page 211 is where I had my a-ha moment. https://cses.fi/book/book.pdf

When it talks of 'm' the factor == m in the solution I used.

Here is my demo:
