Well in a couple weeks (April 3) I will be 49 ... and 492007 is prime.

But alas 04032007 and 20070403 are both composite.

BUT 3042007 is also prime (The third of April, 2007).

49 is a perfect square. 7, the last digit of the year 2007.

2007 is 3 squared times 223. 2+3+3 = 7

200749 has only 2 factors: 367 and 547; both end in 7.

Think I better go to Vegas on my birthday ... I'm feeling lucky.

My birth date is 18.10.87, and 181087 is prime :)
So I don't have to bother about each birthday :victor:

Four of the 14 different forms (all I can think of) of my b-day are prime.

We only accept Y-m-d and d.m.Y :mad: !
:wink:
OK, I will make an exception and accept d.m.y (since dmy is the only prime one for me...:rolleyes:)

Congrats, gramps! :grin:
So, an April Fool's Day birthday, huh? That's got to be annoying.
"What's your birthday?" "April 1st" "No, really, don't joke around, what is it?"

P.S. I don't know the exact second of the birth but if I can assume it is:

2007-04-01 07:19:57

then the exact birth time would be a prime number.

Wow, I've just found that M41678387 has a factor: 6624567296027728471 . That's my third factor in ten days! :banana: Now I have done more than 10 P90 years in factoring!

(OK, that's not too much of an achievement, but it feels great anyway!)

Scream if you wanna go faster!
