Thread: Prime Birthday numbers.

  1. #1

    Default Prime Birthday numbers.

    Okay, this thread is for people who wants a prime birthday factorization. I'm trying some sieve methods and such. I'll keep doing them until I get tired.

    Anyways, my birthday digits are 8191983, month-day-year, where month is 2 digits, day is 2 digits, and year is 4 digits. I recompose that into a prime factorization of: 3*19*143719

    In a day-month-year (1981983) format I get: 3*660661.

    Is that cool or what? Look at the largest prime in each factorization. Notice anything? Yep, the digits sum up to 25. Not only that, 3 occurs in both factorizations and 19 is my day of birth. What do these numbers mean? The hell if I knew, but maybe I can give you guys some lucky numbers.

    So if you don't mind posting your birthday publically, go ahead...otherwise scram.

    EDIT: This sounds confusing, but only if you've never taken number theory before. The fundamental theorem of arithmetic says that every number is built out of multiplicative powers of primes. Prime numbers (integers, though complex numbers do have primes) are positive numbers greater than 1 that are divisible by 1 and itself. Here's quick trivia, 2 is the only even prime...making it the most unique of all primes. There are infinitely many primes. No matter what number you give me, I can break down that number into prime factorization (though it can take a while given the size of the number). Just to let you guys know, there is a prize of about $1 million US that goes out to those who can find primes that are amazingly large, like those with 100 billion decimal digits.

    Anyways, you guys probably won't understand what the numbers mean and how I got them unless you've taken number theory for about 2-3 months. But enjoy!

    9081987 = 23*3*43*3061

    Not sure what those numbers mean, but eh. You can make something magical out of them.

    Well, I edited my topic.

    Unfortunately, your numbers exceed those on any lottery ticket, so I can't say they're lucky. I guess you can sum up your digits (like 61 = 7) and get something out of them.

    I'm just a geek who's a little bored right now...so yeah.

    Thanks, but I don't agree with prime birthday factorization.

    5-22-1985?

    Try that one, I'll see if my prime factorization helps me unlock the secrets to rule the galaxy...
    Anyone can rule the world if they give it the ol' college try.

    5*1044397

    Congratulations DaremihC, since 1044397 is the current largest prime among Birthdays, you are currently king! Can anyone else top this prime? Only 7 digits long!

    1st October, 1984
    10011984
    = 2*2*2*2*3*167*1249

    And for some others, since I'm bored...

    22nd August, 1986
    7221986
    = 2*29*41*3037

    January 31st, 1989
    1311989
    = 7*23*29*281

    October 11th, 1988
    10111988
    = 2*2*2527997
