Abstract
Let x 1, x 2, ..., x n be positive integers. It is well-known that every sufficiently large integer can be represented as a non-negative integer linear combination of the x i if and only if \(\gcd(x_1, x_2, \ldots, x_n) = 1\). The Frobenius problem is the following: given positive integers x 1, x 2, ..., x n with \(\gcd(x_1, x_2, \ldots, x_n) = 1 \), compute the largest integer not representable as a non-negative integer linear combination of the x i . This largest integer is sometimes denoted g(x 1,..., x n ).
