Isn’t every number divisible by 7?

Yes technically almost every number is divisible by another in some way and you’re left with a remainder that spans plenty of decimal places.

But common parlance when something is said to be divisible is that the end results is a round number…

Yup, this is just a coordinated smear campaign from Big Integer.

So what? Being a prime number doesn’t mean it can’t be a divisor. Or is it the string of 9s that’s supposed to be upsetting? Why? What difference does it make?

The above is 42857 * 7, but you also get interesting numbers for other subsets:

     7 * 7 =     49
    57 * 7 =    399
   857 * 7 =   5999
  2857 * 7 =  19999
 42857 * 7 = 299999
142857 * 7 = 999999

Related to cyclic numbers:

142857 * 1 = 142857
142857 * 2 = 285714
142857 * 3 = 428571
142857 * 4 = 571428
142857 * 5 = 714285
142857 * 6 = 857142
142857 * 7 = 999999

Phew, for a moment I worried that 2.9999… was divisible by 7 and I woke up in some kind of alternate universe
