Jacobi symbol Jacobi symbol The Jacobi symbol is a generalization of the Legendre symbol. Introduced by Jacobi in 1837, it is of theoretical interest in modular arithmetic and other branches of number theory, but its main use is in computational number theory, especially primality testing and integer factorization; these in turn are important in cryptography. For any integer "a" and any positive odd integer "n", the Jacobi symbol is defined as the product of the Legendre symbols corresponding to the prime factors of "n": where is the prime factorization of "n". The Legendre symbol is defined for all integers "a" and all
