I Am Fascinated By Prime Numbers

Personal Stories, Advice, and Support 233 People

    I AM 177

    I happened on this group by 'accident' (although, in reality, there are really no accidents). Anyway, if I am permitted to join, that would make me no. 177 (another prime number). I am also writing this on Saturday, the seventh day of the week (yet another prime).

    I Think That I Must Have Lost Some IQ Points!

    When I was a kid in both Junior-High and High School, I was tested, and my IQ scores were 165 and 185. I could figure out puzzles and riddles, decipher codes, analyze situations, size up people, and do a plethora of 'brainy' other stuff way back when. Later, I gave birth to 5...

    I almost became a computer criminal at 17 years

    old because of a fascination with prime numbers. I had just read Rivest Shamir and Adlemans article in the 1979 issue of Scientic American on Nondeterministic Polynomail Time Problems. In it they detail the workings of public key cryptosystems, that are used in your browser...

    The Only 'even' Number That I Like Is 2

    I don't know how I got into the 'prime number thing', but now, when I set my microwave oven or dryer for time, it has to be a prime number. I'm not totally obsessed with prime numbers...they can just be odd numbers; but even number drive me nuts... with the exception of 2, which...

    I don't know that it a 'fascination' really,

    but I'm always noticing them. My friends just roll their eyes when I tell them that their phone number, or address is prime.

    Is 2,904,897 A Prime Number?

    This little trick may win a bar bet someday and it's inexplicable on the surface, so is cool just for that. Well, it's not EVEN, so isn't a multiple of 2, doesn't end in 5, so isn't divisible by 5, but that leaves a lot of ground. In case you forgot, you only have to divide a...

    Why I Love Prime Numbers

    I didn’t always like prime numbers. For Pete’s sake, dividing by 2 is always easier… and 10 is a fabulous number if you’re doing any arithmetical work. I discovered the beauty of prime numbers totally by accident. I inadvertently set a timer for 59 minutes. It just...

    Is 59595 A Prime Number?

    No, silly, any number ending in 5 is divisible by 5. Why did this number come up? It's how many EP points I reached as of today and I've always thought "symmetrical numbers" are cool. BTW, is the number of EP points YOU have a prime number?

    Left Trunctable Primes

    As a counterpoint to my story "Right Trunctable Primes", the curious will be satisfied to know there ARE Left Trunctable Primes as well, which are prime numbers that remain prime when the leading digit is removed successively. Here are some: 2, 3, 5, 7, 13, 17, 23, 37, 43, 47, 53...

    Right Trunctable Primes

    These are strange primes in that, if you successively remove the right-most digit another prime results, BUT even stranger is that if you coninue to do this, every "new [smaller]" number will also be prime. Here's an example: 3797  379   37    3...

    not a prime number, but still interesting:

    if you take any set of three digits and replicate it to give you a number less than 1,000,000 that number will be divisible by 13. For example the three digits 864 replicated becomes 864864 which is divisible by 13 (66528)

    Does 1910194 Mean Anything To You?

    It appears in the book Japa Yoga by Svami Sivananda and I always wondered what its significance is - the book's context isn't explicit. It would have been cooler if it were 1910191. Neither of these 2 are prime numbers, however. FYI the next smaller number which is prime is...
