How to do it as a beginner?

  • Mathematics: This takes me back to school, I thought of two methods - factorisation and trying every number till the smallest - remember we used to do this for finding if the given number is a complete square?

This isn't exactly an advanced question if you know your math, just like predictive isn't difficult if you know your statistics, so go back to basics! 🙂

I'm sure there's a quicker way by just testing the primes, but that would most likely get the LCD easier... Anyhow, it's not too hard to generate 100 or 1000 rows per existing row.
