133 is an n whose divisors (excluding n itself) added up divide φ(n). It is an octagonal number and a Harshad number. It is also a happy number.
133 is a repdigit in base 11 (111) and base 18 (77), whilst in base 20 it is a cyclic number formed from the reciprocal of the number three.
133 is a semiprime: a product of two prime numbers, namely 7 and 19. Since those prime factors are Gaussian primes, this means that 133 is a Blum integer.
You know that nothing you just wrote made any sense, right?
"Blum Integer, 7 and 19 are Gaussian Primes, 133 is 111 and 77 in base 11 and 18" and, "ITS A HAPPY NUMBER"
omfg, how can people be like this
YOU ARENT PROVIDING ANY INFORMATION, YOU'RE LITERALLY JUST DIVIDING NUMBERS USING DIFFERENT METHODS AND SAYING THE RESULT
and fucking happy number, wtf, HOW, WHY, WHO, WHY, WHY.
That's just the maths part of the wiki page describing this number.
I like numbers, you seem to only like yourself, but in a poor way.
Enjoy life, weird ideas, don't get to the Internet if you feelin such a dire compulsion to argue with unknown people about details that don't really matter.
Take my upvote, I insist.
