Web26 jan. 2024 · Fermat's factorization method. We can write an odd composite number n = p ⋅ q as the difference of two squares n = a 2 − b 2 : n = ( p + q 2) 2 − ( p − q 2) 2. Fermat's factorization method tries to exploit the fact, by guessing the first square a 2 , and check if the remaining part b 2 = a 2 − n is also a square number. http://nlvm.usu.edu/en/nav/frames_asid_202_g_3_t_1.html
