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!

Uhhh, I don't get it. So do mine.

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.

Try that one, I'll see if my prime factorization helps me unlock the secrets to rule the galaxy...

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!

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

22nd August, 1986

= 2*29*41*3037

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

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

I could probably do it if it wasn't for my crippling laziness...

There's one problem I see with this.

The american date system, as far as I know, days kinda work up into months, AND NOT THE OTHER WAY AROUND.

Seconds -> Minutes -> Hours -> Days -> Weeks -> Months -> Years

As far as I know, hours don't instantly go into months now, do they?

No, american's use dates as

MONTH/Day/Year

The rest of the world goes Day/Month/Year

being that I am an american... do me!

Yes, America screwed up and now they're trying to cover it up by saying they did it intentionally, and now they're stuck with that sucky system.

I'm very curious, so could you figure out mine, too? If I didn't hate math, I'd do it myself.

It does for me...

1044397 Nine is the only number in my original birthdate... this sucks, I'm leaving...

Keep up the good work, and sorry you had to primefactoritize my crappy numbers...

Chris, you are very lucky. Your birthday is the first that is a prime number. So 1121987. Wow!

Surprisingly, yours is the first birthday to be built out of primes of only 2 decimal digits or less.

71587, which I'm too lazy to factor, as neither 5, 3, 9, 10 nor 2 evenly go into it.

Well, 10 isn't prime...but eh. It would've taken you a while to get to the next prime, which is 107. But without further ado:

7151987 = 107*66481

I was just using trial and error with calcX.x; that 71 was a surprise though.

and I sure hope seedrankLou was right and 1093 is primeX.x; it took a long time to get to 181.

Eh, I probably did one or the other or both wrongxD

I'd personally have issues with using months, as their lengths often vary. Even so, the International system of DD-MM-YY is also irritating to me. I prefer YY-MM-DD, because it is easiest to quicksort files and other things like that. :p
