Wouldn't Zero be the most perfect number?

It's neither odd or even.

You can add, subtract, divide, multiply, or cube it by itself and it never changes.

Without it there would be no binary system.

And if the Arabs hadn't shared it with everyone I would have to balance my checkbook using Roman numerals (which would realy suck Moose Wang).

Ah! Now I understand. I can just imagine the computer resources needed to factor every number and test to see if it's perfect. I wonder how far they've tested? I would guess somewhere around 10 digits.

Nah, they passed 10 digits back in 1588 using their Super Computers...

#48 discovered in 2013, it is 34,850,340 digits long!

the p is used in this Formula
2^(p−1) × ((2^p) − 1) where ((2^p) − 1) is a Mersenne prime

0 can not be a perfect number it doesn't pass the first rule.


a perfect number is a positive integer that is equal to the sum of its positive divisor, excluding itself
0 x 1 = 0
0 x 2 = 0
0 x ... = 0
it has an infinite number of divisors, so the sum of it divisors is infinite...

1 + 2+ 3+ 4+ ..+ ...

edit:
I borrowed a calculator and put it up on my website
it calculates all the Factor or Divisors of a number, up to 20digits long..

Lets see now, with 1 inch margins you can get 4389 characters on an 8.5 X 11 page using courier 10 font. That means the number printed out requires 7,941 pages or 26 volums of about 300 pages each which printed on two sides of 20# paper will weigh 158.8 pounds not counting the covers. I wonder if the digits meet any of the statistical tests for random numbers?

@Everyone

WOW !

I dare not ask how you guys would give a statistical analysis for one of our models :-)

Ahh I never trusted Statistics..
90% of Statistics are manipulated numbers up anyway! and the other 20% are probably fudged.

Re your comments on the DEC PDP8 - many happy memories for me. We installed one at my college in 1973. It was programmed in assembler using punched tape. We also had a Hawker Siddeley DCC2 (machine code only programming) and an ICL 1903A main frame using Algol and Fortran, amongst others, on punched cards.

The DCC2 could sit on a bench, the PDP8 was the size of a small wardrobe and the 1903 filled a complete room. The humble Raspberry Pi can out perform all of these and you can comfortably stick it in your pocket. We have come a long way in the last 50 years.

I remember when the HP-35 hand-held scientific calculator first came out. 1969 or 1970 I think. The professor who had worked on the ENIAC compared the two. The HP was orders of magnitude better. Then he said they would be giving them away free in cerial boxes in 10 years. He was right.
