This is a very powerful This is an excellent video explaining the concept of Fermat's Little Theorem. Subscribe to our channel for more such videos. Fermat Theorem is one of the most popular concepts students use while trying to solve remainder problems in MBA exams like CAT, GMAT, XAT etc. Fermat Theorem is a very powerful concept which can be used to break down complex remainder theorem problems into easier sub parts. A basic understanding of modulus and GCD is necessary to understand the theorem well.

Find the least residue (modulo p) using Fermat's Little Theorem; or find the remainder when dividing by p. We start with a simple example, so that we can easily check the answer, then look at much bigger numbers where the answers cannot be directly checked on a calculator.

Solution to test exercise: p = 71, q = 89 n = 6319 phi = 6160 e = 3 d = 4107 "Go" = 715 (3320 encoded) "Up" = 2116 (5350 encoded) References: Modular Arithmetic: http://artofproblemsolving.com/wiki/index.php/Modular_arithmetic/Introduction Euclidean Algorithm: http://artofproblemsolving.com/wiki/index.php/Euclidean_algorithm Euler Totient Function: http://www.artofproblemsolving.com/wiki/index.php/Euler's_totient_function Exponentiation By Squaring: https://en.wikipedia.org/wiki/Exponentiation_by_squaring Euler’s Theorem: https://en.wikipedia.org/wiki/Euler%27s_theorem Fermat’s Little Theorem: https://en.wikipedia.org/wiki/Fermat%27s_little_theorem ---There are many fascinating concepts and theories to choose from. Why did you pick this one? I picked RSA encryption as my topic because it is fundamental to the security of the internet, something which most people take for granted. Everyone should know why it is safe to send messages across the internet without fear of them being stolen. Since RSA is one of the primary encryption methods used by modern computers, people should know how it works. I also felt that this topic would be something that the majority of people don't actually know, so it would be beneficial to have a video such as this that is accessible for the average person to understand. I also make it a point to add in a clear, concrete example of why RSA encryption works, so that someone who watched the video could visualize the way RSA protects our information. ---Tell us about yourself! Why do you believe that it is important to study mathematics, life sciences, or physics? I have a lot of experience in math. Ever since I was young, math has been my favorite subject. In high school I took an accelerated math course through multi variable calculus, and I also participated in many math competitions such as USAMO. The reason that studying STEM areas is so important is because they literally represent the future progress of our society. Each discovery and breakthrough furthers our society's knowledge and gives us access to new technology to improve the quality of life of everyone on the planet. Furthermore, STEM jobs pay very nice salaries, making it very easy to have a comfortable life as a STEM worker. ---What specific area(s) of mathematics, life sciences, or physics would you like to pursue in the future and why? Currently I am not sure exactly which areas of math I will pursue in the future, since I could see myself in either a pure or an applied field. But hey, isn't that what college is for? ---Tell us about a teacher who inspired your interest in mathematics, life sciences, or physics. What is the teacher's name? What did that teacher do to develop your passion for learning and discovery? The teacher who inspired me the most was my math team coach, Mr. Curt Michener. He convinced me to join the math team, and eventually I caught the math bug. If it weren't for him, I would have never truly realized my love for mathematics. He also provided me many opportunities to participate in math competitions, such as AMC, Math League, and Moody's Mega Math Challenge. I couldn't have done it without Mr. Michener. ---If you win the Breakthrough Junior Challenge, your school will receive a new, cutting-edge science lab from Cold Spring Harbor. How would this lab benefit your school? The lab would reward those who worked hard in their science classes, hopefully causing more people to fall in love with science. That would be great for my school because we always need more science majors.

Fermat and Euler To get certificate subscribe: https://www.coursera.org/learn/crypto ======================== Playlist URL: https://www.youtube.com/playlist?list=PL2jykFOD1AWYosqucluZghEVjUkopdD1e ======================== About this course: Cryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two parties generate a shared secret key.

The bizarre theorem proposed by Fermat in 1640, and proven almost 100 years later by Euler, as a non-applicative gem of pure math, has been dusted off by modern cryptography, and is now exploited in powerful protocols that enable the miracle of cyber commerce. Looking back the proof is so simple, one wonders why it took so long? Is there more math insight there -- that we don't see, but our adversaries do?

Fermat's Little Theorem was observed by Fermat and proven by Euler, who generalized the theorem significantly. This theorem aids in dividing extremely large numbers and can aid in testing numbers to see if they are prime. For more advanced students, this theorem can be easily proven using basic group theory.

There are two important theorems that make the job of understanding powers in modular arithmetic much simpler. These go back to Fermat and Euler. We apply these to the nice problem of deciding z mod 13. Fermat's result helps us understand powers to a prime modulus. Euler's result relies on understanding the interesting Euler phi function, and is a generalization of Fermat's. As usual we like to illustrate theorems with explicit examples.

Professor Sir Andrew Wiles of Oxford University has been awarded the 2016 Abel Prize – one of the highest honours in mathematics – for his proof of Fermat’s Last Theorem. But what was this famous theorem, and why did it exercise the greatest minds for more than 300 years? Marcus du Sautoy, Simonyi Professor for the Public Understanding of Science at Oxford University, explains.
