A circle with 6 numbers

  1. Oct 5, 2004 #1
    hi,

    i've got a question (don't know, if this is the right forum for this.. but i think, it isn't really a brain-teaser)

    My biology teacher told me this and said, that he doesn't know anything about the reason for them.
    It isn't a homework or something like that, but I and my friends are very interested in solving the "problem".. or even being able to explain it to oneself.

    I've got the Numbers written in this circle:

    [tex]\begin{matrix}& 7 & 1 & \\ 5 & & & 4 \\ & 8 & 2 & \end{matrix}
    [/tex]


    When i read it to the right, I get for example the number 285714

    When i multiplicate this with 2, i get ..
    The amazing thing of them is, that 285714 is readable in that circle, too.

    That works with the factor 3; 4; 5, 6; too.

    142857 * 2 = 285714
    142857 * 3 = 428571
    142857 * 4 = 571428
    142857 * 5 = 714285
    ...

    I tried to explain this to myself, but i didn't really understand it.

    Can one of you please tell me why this works with that numbers?
    Is contingency or _must_ it be like that?

    thnx for help!

    greets

    ps: sorry for my bad english, but this is not my mother-language....
