Mine's bigger than yours

[Bob]

Yes, it's a geeky battle of the largest prime number!  Just what you expected right?

Let's see who has the largest prime number!

(audience ooooo's and ah's)

A prime number is a positive number divisible by only itself and 1 — 2, 3, 5, 7 and so on.



I choose...
2 to the 30,402,457th power minus 1!!!!


What's your pick?  If you dare!....










(Yes, it's a guy thing.)

[phil13]

Oh, yes, I dare...

Infinity. For you cannot divide infinity by any number other than 1, and that is infinity.

Booyah!

Let us review what we learned in Kindergarden real quick here. Infinity is not a "number" it is a concept, just like zero is not a number but a concept. Since infinity is not a number it cannot qualify as a prime number.


And Bob, I don't have a computer powerful enough to calculate the larget prime.

[BoliverAllmon]

yours is of course the largest. That number was only recently found. hard to believe that people are still looking for these insane numbers.

Bob, what is the smallest number?

*great minds think alike!!*

1

[Motrax]

2

1 doesn't count as a prime number. ( https://primes.utm.edu/notes/faq/one.html )

wait.  isn't it 2 to the 30402457th  -1?   or mersenne 43.  i am now officially a genius.  thanks motrax.

wouldn't it be 2  to the - 30402457th power plus a microscopic fraction (not sure how to write that one) of 1?

[pianistimo]

you idiot.  (i'm joking here - because i only passed algebra and didn't even make it to geometry)  he just said in the article that one can't be a prime number.  even i understand that!

somehow, i do not think i should post here anymore because of faulty logic - and perhaps an aversion to anyone thinking i've got a 'big?' head?  or should i say that?  well i have a small head and a big mind - but it is really messed up.  i mean the wires get crossed a lot and blah blah blah and btw i am a woman and i'm not trying to prove anything. 

[BoliverAllmon]

geez, I am an idiot. I real all about one not being a prime and that a prime had to be larger than one. LOL for whatever reason it did not register in this brain of mine. I must have too much Bach and Schubert on the mind (auditions coming up)

[pianistimo]

maybe you're right, though.  a microscopic FRACTION of one isn't one.  so, you may have just discovered something.  do it anyway.  break the rules.  that's how things are discovered. 

[I Love Xenakis]

Yeah, you didn't say integer.

I skipped kindergarten. 

Besides, I know that that number is so immensely high that no one will be able to top it.

Let's see who has the largest prime number!

Let the largest prime number of Bob be b_n

Consider the set S : { b : b is prime} that contains all primes <= Bob's prime.

Then L =  b₀.b₁....b_n + 1 is either prime and bigger than b_n and I win. Or there exists a prime that divides L, call it L' which is prime and, by construction, no elements of S divide L, is not in the set S and thus is a larger prime than b_n

Unforunately the margin isn't big enough to finish the trivial exercise of determining the value of L and L' so I'll leave that as an exercise

its funny, because in a-maths class we were just learning sets.. everytime the teacher said 'sets' it sounded like 'sex', and we were wondering.. how do you have sub sex and disjointed sex??

Oh ya?

Argh!!! The biggest size font is 99!

[pianistimo]

wow.  zip codes and #99 (sounds like a fire company number).  you can tell people here are realistic about math.  they only want to type numbers that have some quanitfiable reason for being.

Huh? I'm afraid I don't understand.

[pianistimo]

consider the set S= {97259}  wow, first time i've used brackets in a long time.
ok.  now use font #99 

that will give you a prime example of how to obtain the LARGEST prime number.  you see, you are my type of thinker.  it eliminates all the stuff about 'to this and that power.'  who knows what really is to that power.  my calculator breaks at that number.  is that why it's the highest known.  because, really, who has time to figure the next number.  and, who has been going around breaking all the calculators?

*admits to secretly coming back to this thread and trying to do the math.
