But what about 33333331? Is it a prime?
It turns out not to be, because we have
17 × 19607843 = 33333331
It follows that we can never trust a pattern just because it looks like it might continue!
Very interesting sir.
Thank you Sir
37 itself is interesting, and so are 37037, 37037037, etc. for similar reasons.
These are in pipeline. Thank you for your suggestion.
Wow…like this we can create more square numbers!!
Thank you Sourav.
Wow! Next time around, it’s Math for me!
