In mathematics, specifically group theory, Cauchy's theorem states that if G is a finite group and p is a prime number dividing the order of G (the number of elements in G), then G contains an element of order p.That is, there is x in G such that p is the smallest positive integer with x p = e, where e is the identity element of G.It is named after Augustin-Louis Cauchy, who discovered it in 1845.
