When they are both large, for instance more than 2000 bits long, randomly chosen, and about the same size ( but not too close, e. g. to avoid efficient factorization by Fermat's factorization method ), even the fastest prime factorization algorithms on the fastest computers can take enough time to make the search impractical ; that is, as the number of digits of the primes being factored increases, the number of operations required to perform the factorization on any computer increases drastically.

The statement of the more general Chebotarev theorem is in terms of the Frobenius element of a prime ( ideal ), which is in fact an associated conjugacy class C of elements of the Galois group G. If we fix C then the theorem says that asymptotically a proportion | C |/| G | of primes have associated Frobenius element as C. When G is abelian the classes of course each have size 1.

When we have generated enough of these relations ( it's generally sufficient that the number of relations be a few more than the size of P ), we can use the methods of linear algebra ( for example, Gaussian elimination ) to multiply together these various relations in such a way that the exponents of the primes on the right-hand side are all even:
