@thatguyalex2835 2 года назад

Unrelated, but a math opinion: Why do we use 10 in our counting system? Yes, I know we have 10 fingers, but not counting our thumbs, each hand has 12 phalanxes (segments). Plus, 12 is highly divisible.

@ERROR-ei5yv 2 года назад

@@thatguyalex2835 Long story short: just cuz it stuck. I agree base-12 would be better, but since pretty much all of modern math is written in base 10, it would be practically impossible to switch, and base-10 happened to be the base we stuck with. we just as well could have gotten stuck with the sumerians base-60, or roman numerals

On these ten years of Numberphile, I've only been on this journey for the last four or five years, but I hope see where this channel goes over at least another decade to come as I've very much enjoyed the ride so far!! As for the last decade of Numberphile, we've seen Matt Parker lose all of his hair, while vampiric James appears not to have aged one bit. The former had a not-so-magic magic square named after him and has published at least one mathematics-themed book -- as quite a few other Numberphile contributors have as well (Simon Singh, Alex Bellos, and I believe Hannah Fry also to name just a few)

@orisphera 2 года назад

Here's another way to count the index that I found myself but I think someone must have found it before: for each prime factor p raised to the power a, compute (p**(a+1)-1)/((p-1)*p**a) (this expression can also be written as (p**a*p-1)/(p**a*(p-1))) and multiply the results together. It shows that the index of the product of coprime numbers is the product of their indices

Are there any friendly numbers that have an index less than 2, ie is there any significance to 10 having an index less than 2 (ie less than a perfect number)?

@maty2faty204 2 года назад

my thoughts exactly and being less than two give an unique fraction and are there odd numbers that are frendly

@killerbee.13 2 года назад

Numbers with index less than 2 are called "deficient" numbers. The first few are 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 19, 21... The smallest known deficient friendly numbers are 135 and 273, with indices 144/135=16/15 and 297/273=99/91. OEIS only lists known friendly numbers up to 372, so I couldn't find more than that easily. Given that some of the numbers which we don't know if they're friendly are also deficient (like 10), 135 may not actually be the smallest deficient friendly number.
