As long as I still have a calculator I think we can manage up to, idk, 400 ? 500 ?

I still just increment the numbers so far along the odd numbers.

You mean 20, though the other 10 is less capable.

Additional rule:

If you are posting a prime, you must check the previous answer.   This should be trivial, for at this point not many people know these off the top of their heads, and will have a list in front of them.    Only correct/comment on incorrect ones.

I suppose the problem sometimes comes when two people post simultaneously at the same time.

Anyway :

That is, indeed, a prime.

 

So is 283, I hope.

293 is the next prime after the indeed correct previous un-evenly-divisable number, 283.
