The honorary even number.

So you're saying there is one? Because the line that's replaced here is Tighten saying "There's no Queen of England" with the point of the scene being showing he's dumb for thinking something that does exist is like the other mythological things listed

[–] daniyeg@lemmy.ml 34 points 6 months ago (1 children)

there's no Queen of England though, Titan was just ahead of his time.

[–] kakito69@sh.itjust.works 11 points 6 months ago (1 children)

Omg he predicted her death????

There hasn't been a Queen of England since the Acts of Union when the title was replaced with Queen of Great Britain.

I’ve only seen the memes.

I thought that character was a she.

Huh.

[–] edinbruh@feddit.it 8 points 6 months ago

This is a good opportunity to go watch megamind

[–] FakeGreekGirl@lemmy.blahaj.zone 2 points 6 months ago

You should watch the movie. It's all kinds of fun.

31521281 = 11 × 17 × 59 × 2857

11 × 17 = 187

11 × 59 = 649

11 × 2857 = 31427

17 × 59 = 10003

17 × 2857 = 48569

59 × 2857 = 168563

17 × 59 × 2857 = 2865571

11 × 59 × 2857 = 1854193

11 × 17 × 2857 = 534259

11 × 17 × 59 = 11033

11+17+59+2857+11033+534259+1854193+2865571+168563+ 48569+10003+31427+649+187=5527398≠31521281

17 × 59 = 10003

you've got an extra zero in there, and you forgot the 1, but the rest of your divisors match my crude brute-force approach:

>>> n=31521281
>>> d = [ x for x in range(1,n//2+1) if not n%x ]
>>> d
[1, 11, 17, 59, 187, 649, 1003, 2857, 11033, 31427, 48569, 168563, 534259, 1854193, 2865571]
>>> yours=list(map(int,"11+17+59+2857+11033+534259+1854193+2865571+168563+48569+10003+31427+649+187".split("+")))
>>> set(yours) - set(d)
{10003}
>>> set(d) - set(yours)
{1, 1003}
>>> sum(d)
5518399

same conclusion though: 5518399 also ≠ 31521281

bonus nonsense

>>> isperfect = lambda n: n == sum(x for x in range(1,n//2+1) if not n%x)
>>> [n for n in range(1, 10000) if isperfect(n)]
[6, 28, 496, 8128]

(from https://oeis.org/A000396 i see the next perfect number after 8128 is 33550336 which is too big for me to wait for the naive approach above to test...)

spoiler more bonus nonsense

>>> divisors_if_perfect = lambda n: n == sum(d:=[x for x in range(1,n//2+1) if not n%x]) and d
>>> print("\n".join(f"{n:>5} == sum{tuple(d)}" for n in range(10000) if (d:=divisors_if_perfect(n))))
    6 == sum(1, 2, 3)
   28 == sum(1, 2, 4, 7, 14)
  496 == sum(1, 2, 4, 8, 16, 31, 62, 124, 248)
 8128 == sum(1, 2, 4, 8, 16, 32, 64, 127, 254, 508, 1016, 2032, 4064)

What about 2^31521281 - 1, I'm pretty sure that's a perfect odd number

[–] tb_@lemmy.world 15 points 6 months ago

In number theory, a perfect number is a positive integer that is equal to the sum of its positive proper divisors, that is, divisors excluding the number itself. For instance, 6 has proper divisors 1, 2 and 3, and 1 + 2 + 3 = 6, so 6 is a perfect number. The next perfect number is 28, since 1 + 2 + 4 + 7 + 14 = 28.

33550336 is pretty odd. look at those pairs. they must be fuckin.

It's ok 69. You're perfect just the way you are <3

[–] zarathustrad@lemmy.world 3 points 6 months ago

69 is a Nice number.

[–] Silentiea@lemmy.blahaj.zone 1 points 6 months ago

I mean... Yes? Yes. Yes, right?

I have a proof, but this comment box is too small to contain it.

[–] ChaoticNeutralCzech@feddit.de 3 points 6 months ago

While you're at it, solve the "all perfect numbers end with a 6 or 8" conjecture.

Perfect numbers are number theory not numerology

[–] Pulptastic@midwest.social 2 points 6 months ago (1 children)

I mean kinda? We're assigning importance to a neat coincidence.

[–] Silentiea@lemmy.blahaj.zone 2 points 6 months ago (1 children)

On the one hand, sure.

On the other hand, a lot of significant things in math and science came about because someone noticed and then studied a neat coincidence.

[–] Pulptastic@midwest.social 1 points 6 months ago

Maybe it's just a nomenclature thing for me. Calling it a perfect number makes me think of the dudes in Pi.

5+1=6, not 5?

Ty for checking my work.
