The Jacobi symbol is defined as the product of the Legendre symbols corresponding to the prime factors of n. The Legendre symbol is defined for all integers a and all odd primes p. The Jacobi symbol reduces to the Legendre symbol when n is a prime. The Legendre symbol is implemented in the Wolfram Language via the Jacobi symbol. - See more

For any integer a and any positive odd integer n, the Jacobi symbol (a/n) is defined as the product of the Legendre symbols corresponding to the prime factors of n: See more
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 See more
The Legendre symbol (a/p) is only defined for odd primes p. It obeys the same rules as the Jacobi symbol (i.e., reciprocity and the supplementary formulas for (−1/p) and (2/p) and multiplicativity of the "numerator".)

The above formulas lead to an efficient O(log a log b) algorithm for calculating the Jacobi symbol, analogous to the Euclidean algorithm for finding the gcd of two numbers. (This should not be surprising in light of rule 2.)
1. See moreThere is another way the Jacobi and Legendre symbols differ. If the Euler's criterion formula is used modulo a composite number, the result may or may not be the value of the Jacobi symbol, and in fact may not even be −1 or 1. For example, See more

Legendre symbol - Wikipedia
• The Jacobi symbol (a/n) is a generalization of the Legendre symbol that allows for a composite second (bottom) argument n, although n must still be odd and positive. This generalization provides an efficient way to compute all Legendre symbols without performing factorization along the way.
• A further extension is the Kronecker symbol, in which the bottom argument may be any integer.Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 6 mins
Definition: The Legendre symbol is a function of two integers a and p, written a p . It is defined for a ≥ 0 and p an odd prime as follows: a p = 1 if QR(a,p) holds; −1 if QNR(a,p) holds; 0 if (a,p) …
