This Prime Factor program is adapted from

Sinclair Cambridge Programmable

Mathematics Program Library on Page 23.6

To work on HP-12C Platinum with ALG mode

——————————————————————-

Example: FIX 0

537

537 [R/S] 3 [R/S] 179 [R/S] 1

Answer: Prime factor of 537 is 3 and 179

——————————————————————

91991

91991 [R/S] 67 [R/S] 1373 [R/S] 1

Answer: Prime factor of 91991 is 67 and 1373

———————————————————————

Program: 12C Platinum ALG mode

Remark:

With this Algorithm the computation speed is slow on physical 12C Platinum where

The emulators will run much faster.
