dedicated to the number 153

my favorite number is 153 because it has so many weird properties

153 = 1^3 + 5^3 + 3^3 (sums of the cubes of its digits)

153 = 1! + 2! + 3! + 4! + 5!

1 + 5 + 3 = 9 = 3^2 (sum of the digits is a perfect square)

1 + 3 + 9 + 17 + 51 = 81 = 9^2 (sum of divisors is a perfect square)

153 + 351 = 504; 504^2 = 288 x 882 (this is my favorite property)

153 / (1 + 5 + 3) = 17 (divisible by the sum of its digits)

153 = 3 * 51

135 = 1^1 + 3^2 + 5^3 (if you rearrange the digits of 153 to make 135 u get this strange pattern)

p (153) = p (15) * 3! (where p(x) is the number of primes up to x

153 is the 17th triangular number (ex.


153 is the 9th hexagonal number (ex.

i was just going to say that this thread would be sticky quality if it had good music
and then it loaded
o_O

im hoping someone stickies this thread

its one of the coolest numbers out there

SO MUCH MATH
I CAN FEEL MY IQ RAISING JUST BY LOOKING AT THIS THREAD

lol

ive been really into number theory lately so ive been trying to find all kinds of cool stuff about numbers

making a proof for a number theory problem is hard tho

gotta make alot of computations to make sure ur not fuking up

All for stickying this thread say "Aye" (minimum required; 6)

AYE

aye

aya

aye

lol no
but i agree its a cool number

Ent voted twice, I'm changing it to 6

cant wait to see htis thread be stickied

aye

fag

my favourite number is 2 cuz
1+1 = 2
2-2+2 = 2
2 +4 - 4 =2
4 - 2 = 2
8 - 4 - 2 =2
16 - 8 - 4 - 2 = 2
32 - 16 - 8 - 4 - 2 = 2
1 + 1 + 1 - 1 = 2
u see it has so many thingiess. ?
and im sure there are alot more if u search for them....
