My solution, fun challenge!

Here's my take on the matter (I considered 1 to be a prime).

I decided to take a more dynamic approach and used an iterative macro.

It works for checking numbers up to 1 million (it does 1000 iterations for this as that is the square root of 1 million).

Fun! 🙂

Challenge #187.PNG

Here's a relatively straightforward solution.

However, it's not very feasible if we were to start with a larger number (>10000).

For scaling up, a better solution might be to use a batch macro that tests the divisibility of each new number by previously found prime numbers. I'm not sure if that's possible though.
