Post: Hi everyone ,I have a number and need some help for it's integer factorization. The 200 digits number comes from the book "In Code: A Mathematical Journey" written by Sarah Flannery and her father. Because the author claim that we can't factor this number even with the supercomputer. But RSA-200,the number almost the same size had already been factored way back in 2005,and a much bigger number RSA-768 which has 232 decimal digits had been factored in 2009. So I am looking forward to having your kind help in this regard The 200 digits number from the book "In Code: A Mathematical Journey": 31580479476026838343434028711320725847154882228947750154281522280836834473689746760598075754629059483639555637314474524275903519617611963787093324474266058093181460871296266561056469547820922800384429 Best regards brianwu21 |
