Historical Background of Euler’s Theorem

Euler’s Theorem Formula

Proof of Euler’s Theorem

Euler’s theorem is named after the Swiss mathematician Leonhard Euler. Euler made numerous contributions to various branches of mathematics during the 18th century, and his work laid the groundwork for much of modern mathematics. Euler’s theorem specifically relates to modular arithmetic and the concept of totient function.

The theorem itself is closely related to Euler’s earlier work on Fermat’s Little Theorem. While Fermat’s Little Theorem states a special case of Euler’s theorem, Euler’s theorem provides a more general formulation.

Euler’s Theorem

Euler’s Theorem states that for any integer a that is coprime with a positive integer m, the remainder of aϕ(m) divided by m is 1. We focus on proving Euler’s Theorem because Fermat’s Theorem is essentially a specific instance of it. This relationship arises because when p is a prime number, ϕ(p) equals p-1, thus making Fermat’s Theorem a subset of Euler’s Theorem under these conditions.

Euler’s theorem is a fundamental result in number theory, named after the Swiss mathematician Leonhard Euler. It states a relationship between the number theory functions and concepts of modular arithmetic. In this article, we will discuss Euler’s Theorem, including its statement and proof.

What is Euler’s Theorem?

Euler’s Theorem is a fundamental concept in number theory. It states that if n and a are coprime positive integers, meaning that they have no mutual proper dividers other than m=1, then aϕ(n) and 1 are relative primes in modulo n....

Proof of Euler’s Theorem

Let φ(n) = k, and let {a1, . . . , ak} be a reduced residue system mod n. For some ai in {a1, . . . , ak} Since (a, n) = 1, {aa1, . . . , aak} is another reduced residue system mod n. Since this is the same set of numbers mod n as the original system, the two systems must have the same product mod n: (aa1)· · ·(aak) = a1 · · · ak (mod n) ⇒ ak (a1 · · · ak) = a1 · · · ak (mod n) Now each ai is invertible mod n, so multiplying both sides by a1−1 · · · ak−1 , We get ak = 1 (mod n) or aφ(n) = 1 (mod n)....
