It is defined as the product of the Legendre symbols for an integer a and a positive odd integer n with prime factorization. The Jacobi symbol shares many of the properties of the Legendre symbol, and can be used to simplify computations involving quadratic residues. When n is an odd prime, the Jacobi symbol is equal to the Legendre symbol.3 Sources

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".)

In vector calculus, the Jacobian matrix of a vector-valued function of several variables is the matrix of all its first-order partial derivatives. When this matrix is square, that is, when the function takes the same number of variables as input as the number of vector components of its output, its determinant is referred to as the Jacobian determinant. Both the matrix and (if applicable) the determinant are often referred to simply as the Jacobian in literature. They are named after Carl Gustav Jacob Jacobi
