Oh, that's cool, who would've guessed that 34,850,340 was a perfect numb-
DIGITS?! 34 MILLION DIGITS?!

6 should be a super duper perfect number because not only do you get 6 when you add its proper factors together (3+2+1) but you also get 6 when you multiply its proper factors together (3x2x1) :D

"You've been in this game for too long!" I love this guy. :D

the "We call those people mathematicians" joke was golden, because it was no nonchalant

"Today we're going to do some maths."
Thanks, Maths Parker, for your influential turn of phrase.

The perfect number doesn't exi-

brady must be an honorary mathematician by now

511 does look very 'primey' lol

Wow that intro sentence... I never expected they would do maths on this channel ;D

2,147,483,647 is my favorite number. It's 2^(31)-1 and it's a double Mersenne Prime. It's the maximum value for a signed 32-bit integer, and just last month, for the first time ever, a YouTube video surpassed this barrier in views. For a short period of time, Gangnam Style's view count was actually in the negatives until YouTube changed the view count to a signed 64-bit integer. However, this is rumored to have been caused by Google as a joke.

Tsk! Numberphile, why are you eroding the self esteem of real numbers by popularizing the impossible standards of 'perfect' numbers? Do you know what percentage of numbers can actually meet those criteria?
You do? Nevermind then.

I'm going to say that a number is primey in front of my Number Systems lecturer and see what their reaction is.
18 |
And so, in fact, that pattern, when people spot these prime values in n, giving these numbers prime, only works in one direction *shows a picture of One Direction*
15 |
Ah, Matt is always awesome, thanks for the videos!

Being someone who has previously never learned about Perfect Numbers or Mersenne Primes, I appreciate all the background you provide. I was slightly confused about if n had to be prime or n-1 one had to be prime--so I decided to get out a piece of paper myself and do some exploring. I proved to myself, as you did, that n must be prime. I am continuously satisfied with the patterns that appear in math and I appreciate you exposing them! I wonder though what a practical use for this information would be--or is it just for fun? Even if it is merely amusement, very interesting video!

thanks. also, thanks for the cadence, cogent flow, and positivity in your methods of teaching this. you're not just teaching, your conveying it with a thought to educational psychology and how people learn. grazie.

Stop everything! Numberphile just uploaded a new video!

I LOVE perfect numbers, I was so excited when I saw this video!!

"Some people like looking patterns...we call those people mathematicians." That was amazing.
