    Study Notes

    The Fundamental Theorem of Arithmetic, also known as the Unique Factorization Theorem or Prime Factorization Theorem, is a central concept in number theory. It states that every positive integer greater than 1 can be represented in exactly one way as a product of prime powers, where the primes are distinct and the exponents are positive integers. This means that each composite number can be uniquely decomposed into a product of primes, up to permutation of the primes and their exponents.

    Euclid was the first to take the initial steps towards understanding prime factorization, but it was Kamāl al-Dīn al-Fārisī who made the first explicit statement of the fundamental theorem of arithmetic. Later, Carl Friedrich Gauss provided an important proof employing modular arithmetic in his work "Disquisitiones Arithmeticae".

    One of the applications of the fundamental theorem of arithmetic is the canonical representation of a positive integer. Every positive integer greater than 1 can be represented as the product of prime powers, which is called the canonical representation. This representation is unique and extends to all positive integers by convention.

    Despite the simplicity and elegance of the fundamental theorem of arithmetic, it is not always obvious why it holds true. There are various ways to prove the theorem, including using properties of prime numbers and demonstrating the uniqueness property through the use of lemmas.

    Studying the fundamental theorem of arithmetic provides insights into the nature of prime factorization and helps in developing an intuitive understanding of mathematical structures.
