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
Quote:[STO] 0 ÷ 2 = [INTG]
[STO] 1
[STO] 2
1 [STO] 3
[RCL] 0 - [RCL] 2 =
1 [CHS] [X<>Y] [X≤Y] [GTO] 038
[CHS] 1 [CHS] [X<>Y] [X≤Y] [GTO] 045
[RCL] 1 - 2 =
1 [CHS] [X<>Y] [X≤Y] [GTO] 050
[RCL] 3 [R/S] [RCL] 1 [GTO] 001
1 [CHS] [STO]+1 [RCL] 3 [CHS] [STO]+2 [GTO] 010
1 [STO]+3 [RCL] 1 [STO]+2 [GTO] 010
[RCL] 3 [R/S] 1

Remark:
With this Algorithm the computation speed is slow on physical 12C Platinum where
The emulators will run much faster.
