you a question twice.

So I was hoping you might reply here. If not that's ok.

"Here is one of spinnys primes with the decimal place removed.

2609945

It factors into a "prime" & a "spin-prime".

What are they? "

2609945 = 5 * 13 * 40153, all three of which are prime.

So

26.09945 = 5 * 5.21989

or

26.09945 = 13 * 2.00765

or

26099.45 = 40153 * 0.65

would all seem to fit the bill.

The statement of your puzzle seems to imply that the solution is unique,
which I've shown isn't the case. Maybe you can find another one?


No need you found the answer.

There are rules noone has given me chance to stipulate.


5 & 2 are not allowed as factors. And I doubt RSA have ever used them
either.


Tell me; (hypothetically) you was forced to find multiple factors.
You then had to test the spinny primes, which for large numbers is a
ball ache.

Now, I'm not saying this is a proven thing, but, in terma of a pure
*Brute Force* attack.
would you have performed *more* or "less" calculations?


Also 0.65 <2..

Should I post a really hard one?




Speaking of puzzles, I have another one for you. Your "spin-primes" are
defined with respect to base 10. I don't find that particularly
interesting. What I find more interesting is the set of numbers that are
"spin-primes" with respect to every base simultaneously. Can you
characterize this set of numbers?


First, How do you mean "simultaniously"?
