...is an even number, not prime

perhaps you mean 2^257885161 minus 1

He googled biggest prime.

😁 oops wrong thread

@sistercheese Yes, I do mean minus 1. That's why I used the subtraction symbol before the "1."

Which is a Mersenne prime, by the way.

prime number is a whole number greater than 1, whose only two whole-numberfactors are 1 and itself. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. As we proceed in the set of natural numbers N = {1, 2, 3, ...}, the primes become less and less frequent in general.

I don't think I'll find it, but I'll let you know when humanity finds our next prime.

Good question
The_Ghostess_Lola

So lemme get this straight. Is (2) the only even number that's prime ?

The_Ghostess_Lola

Okay. Pick a prime number between 1 & 50.

Now, go to my webpage and see the number you just picked.

That is the ultimate question.

Very true.  But can you prove it?

∞/∞ =1; ∞/1=∞

An easy one:

Suppose there are only n (finite) prime numbers. Multiply all those prime numbers and substract 1. You have a number (let's call it K) which is not divisible by any of the n prime numbers. Therefore:

a) K is not prime, but is the result of multiplying several prime numbers which are not in our initial conjunct of primes.

Or

b) K is a prime number

So now we have that the number of primes has incread, and will increase indefinetely if you do this an infinite amount of times.
