Having got curious about the mathematical properties of the number 23, I started exploring and here’s what I found interesting from what I have seen on the web:

  • 23 is the smallest prime number with consecutive digits.
  • 23! is 23 digits long.
  • 23 = 14 + 23 + 32 + 41 + 50
  • 1023 – 23 = 99,999,999,999,999,999,999,977 is the largest 23 digit prime.
  • According to the birthday paradox, in a group of 23 (or more) randomly chosen people, the probability is more than 50% that some pair of them will have the same birthday (are we not coming to the topic now ?!!)

Oh by the way, Happy XXIIIrd to me 🙂
