902, 903, 904 all have the same number of factors.


  1. I just did the first factoring of a number that I've done in about 2.5 thousand years or so. Depending on how one is supposed to count factors (I only counted positive integers and not primes), and whether 1 and the number itself are supposed to be counted (I did), I got 8 factors for each. Did I calculate and count things correctly? This was fun, and interesting. Are there other groups of consecutive numbers like this that have the same number of factors?

  2. Probably are others. 1 and the number itself are both counted. So are all primes. I'll post more later.
