RE: Calculate manually with RPN calculator
Another example: To find GCD and LCM
To find GCD ( X, Y ) where X < Y Setup: X [ENTER] [ENTER] [ENTER] Y [X<>Y] Iterations: [÷] (input only integer part) [] [x] display <1 ? NO: [ENTER] [ENTER] [Rv] [Rv] continue Iterations YES: [Rv] Finish (Round to an integer if necessary) ————————————————————————— To find LCM ( X, Y) First find the GCD answer. X [ENTER] Y [x] (GCD answer) [÷] ———————————————————————— Example: GCD and LCM of ( 555, 666 ) To find GCD 555 [ENTER] [ENTER] [ENTER] 666 [X<>Y] [÷] Display 1.2 input 1 [] [x] display 111 ( not <1 ) [ENTER] [ENTER] [Rv] [Rv] [÷] Display 5.0 input 5 [] [x] display 0 (now <1) [Rv] display 111 Answer 111 —————————————————— To find LCM 555 [ENTER] 666 [x] display 369630 111 [÷] display 3330 Answer 3330 ————————————————————— Gamo
