RE: HP 41C Pollard Brent Integer Factorization
A modulo 210 brute force factoring on the HP-67 took 0.1042*sqrt(x) seconds in 1979. The HP-41 averaged 3 times that speed. So your example would take around 58 minutes. (CF "Finding Factors Faster", PPC Journal, mid-Cretaceous epoch, by some old phart)
