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
