WebPartial Factorization: If limit (> 3) is specified, the search is stopped after performing trial division up to (and including) the limit (or taking a corresponding number of rho/p-1 steps). This is useful if one has a large number and only is interested in finding small factors (if any). Note that setting a limit does not prevent larger factors from being found early; it simply … Web17 feb. 2024 · p mod 4 = 3 而Rabin应该需要两个因子的,所以接下来的Rabin派不上什么用场 由于e=7已经和phi1和phi2都有公因子了,不能继续化简指数;而且这个公因子来自p-1
