Everything You Need to Know About Modular
... Definition Two numbers are relatively prime if their prime factorizations have no factors in common. Theorem Let m ≥ 2 be an integer and a a number in the range 1 ≤ a ≤ m − 1 (i.e. a standard rep. of a number modulo m). Then a has a multiplicative inverse modulo m if a and m are relatively prime. Ex ...

... Solution: The fundamental theorem of arithmetic says that all numbers can be factored into a product of prime factors. We test prime factors starting with 2. However, we initially see that the primes 2, 3, 5, 7, 11, 13, 17 do not divide 127. How many prime divisors do we need test? We could stop at ...

Arithmetic
Arithmetic or arithmetics (from the Greek ἀριθμός arithmos, ""number"") is the oldest and most elementary branch of mathematics. It consists of the study of numbers, especially the properties of the traditional operations between them—addition, subtraction, multiplication and division. Arithmetic is an elementary part of number theory, and number theory is considered to be one of the top-level divisions of modern mathematics, along with algebra, geometry, and analysis. The terms arithmetic and higher arithmetic were used until the beginning of the 20th century as synonyms for number theory and are sometimes still used to refer to a wider part of number theory.
