    Yes, I agree that 16 digits is not especially large - certainly not for crypto purposes - but if I was to provide a number which is the product of two 8-digit primes (maybe), how long would it take to find them? What's the algorithm?

    After, sleeping on the problem, it now seems to me the real WTF, of course, is the fact that we're expected to know a 16-digit prime.

    Most of the respondents here have had trouble thinking of a SINGLE digit prime, fer cryin out loud!

  • Steve Jorgensen (unregistered) in reply to Nick

    And a unique 16-digit prime number, eh? I guess that means one that's not the same as any other 16-digit primer number?

    Leading zeros count as digits right?

    0000000000000001

    Done!

    That is not a prime number.

    Just to nitpick: A prime number must have exactly two divisors. These divisors are itself and 1.

    1 has only one and therefore doesn't count.

    How long it takes would depend on the algorithm used. Fairly easy to implement is Pollard's Rho-algorithm, that should factor 16-digit numbers in less than a second.

    To add to that thread, most of the respondents don't even know that 1 is not even a number*, so it is a fortiori not a prime number.

    The first bluescreen picture also appears to be from the UK. The sign behind the kiosk says "Ground carpark". In the US, we usually just saying "Parking"

    It's not from the UK, we don't have Myer or Coles (just above the car park sign) over here. Possibly Australian?

    Definitely Australian.

    Call it even - very subtle, very funny.

  • brett (unregistered) in reply to Nick

    1 is not prime. a prime can be divided by two numbers. one and itself. therefore 1 is not a prime.

    btw, 2 is the odd prime. it's the only even prime therefore it is odd.

  • John (unregistered) in reply to Nick

    Except that 1 isn't a prime number. You need 0000000000000002

  • Jishnu (unregistered) in reply to Nick

    Still you did not get it rite 1 is neither neither prime nor composite

    0000000000000002 would be 'more' appropriate

    That'd work if 1 was prime.

    Main Entry: prime number Function: noun Date: 1570 : any integer other than 0 or ± 1 that is not divisible without remainder by any other integers except ± 1 and ± the integer itself

    hehe.

  • Netham45 (unregistered) in reply to ant

    2 is.

    only 2 numbers that can divide into 2 without a remainder are 1 and 2, making it prime!

    My senior year of high school, I was helping a friend of mine (who was a tech aid for the school) work the bugs out of a new administration program the computer labs were going to use. This was an override program the teacher could use to get the entire class' attention, or just a certain person if need be.

    The teacher hadn't realized we had the program working and we were looking around at other students' screens. The teacher was helping a particular student with something when I looked at my friend and gave him an idea.

    Suddenly, the teacher's monitor went black, and the words, "Enter any 11 digit prime number to continue" appeared.

    After a trip to the math department, the teacher returned to a class that had been laughing the whole time she'd been gone.

    Quoted from http://www.rinkworks.com/stupid/cs_revenge.shtml I would have provided a link, but you would've had to scroll a lot to find it.

    FAIL one is not officially prime number(see below for article). and for that trick to work, you could have picked any of the four other one digit prime numbers, and added leading zeros.

    0000000000000002 0000000000000003 0000000000000005 0000000000000007

    From Wofram Mathematica]: A prime number, p, (or prime integer, often simply called a "prime" for short) is a positive integer p > 1 that has no positive integer divisors other than 1 and p.

    except that 1 isn't a primenumber according to the experts, a prime number can be divided by two numbers 1 and itselves, maybe a little wtf in common definitions?

    i'll just input 17 cause it's the first prime number after number 16

  • M. (unregistered) in reply to Nick

    erm, that's not technically prime. 2 would be, but not 1, it only has one divisor. (1).

    Leading zeros are fine. Shame you still couldn't manage a prime number. Try 0000000000000002.
