Quote:Can someone get 720^20-3 factorized at all (in a calculator context), and only after that factorized quickly? (Same for 720^20-18 and all the others hard variants) I very much doubt it's doable on any 2018-era calculator (let alone "quickly") as 720^20-3 has two 23-digit prime factors and 720^20-18 has a 22-digit prime factor and a 35-digit one. In similar fashion, 720^20-19 and 720^20+19 are both prime. Regards. V. . All My Articles & other Materials here: Valentin Albillo's HP Collection |
