Taking a look at numbers in binary reveals some interesting patterns. Although seems obvious, it was interesting to me when I realized that all prime numbers except 2 end with 1.

Not trying to be a jerk, but why is that interesting? Am I missing something more than all odd numbers end in 1, and primes by their nature cannot be even(except 2, as you mentioned).

  • Just nitpick but all odd numbers end in an odd number, not 1, and all even numbers end in an even number i.e. a multiple of 2.
