6,700,417 - The prime which Proved Fermat Wrong. #MegaFavNumbers

Pierre de Fermat - of "Fermat's Last Theorem" fame - thought that 4,294,967,297, and all numbers of the form 2^(2^n)+1, were prime. But he was wrong! More about Fermat numbers (and primes) - https://en.wikipedia.org/wiki/Fermat_number This video is part of the #MegaFavNumbers project. If

Theory of numbers: Fermat's theorem

This lecture is part of an online undergraduate course on the theory of numbers. We prove Fermat's theorem a^p = a mod p. We then define the order of a number mod p and use Fermat's theorem to show the order of a divides p-1. We apply this to testing some Fermat and Mersenne numbers to se

Very Large Primes and (Almost) Perfect Numbers -- MegaFavNumbers

This is my video submission for the #MegaFavNumbers celebration. As promised in the video, here is the very large number that was simply too big for the screen: 5282945208034002678497845769960721106385426547566030332928651387255812371024044147692699871010305634389030253300042369944654409

Fermat’s HUGE little theorem, pseudoprimes and Futurama

A LOT of people have heard about Andrew Wiles solving Fermat's last theorem after people trying in vain for over 350 years. Today's video is about Fermat's LITTLE theorem which is at least as pretty as its much more famous bigger brother, which has a super pretty accessible proof and which

Why was this visual proof missed for 400 years? (Fermat's two square theorem)

Today's video is about a new really wonderfully simple and visual proof of Fermat's famous two square theorem: An odd prime can be written as the sum of two integer squares iff it is of the form 4k+1. This proof is a visual incarnation of Zagier's (in)famous one-sentence proof. 0:00 Intr
