How do you find the gcd and lcm ?

Craig Diamond says:

Love the recurring decimal function and don’t understand why most calculators don’t have it. Although I still cannot get this calculator to do e^pi x I in complex mode…my sharp 516x gives -23.xxxxxi and my ti-83plus and HP 35s give the correct answer of -1  but this one just gives math error……

NIGGAS says:

Eleanna Proett says:

OMG you saved my calculator from the hammer I was going to use on it.  I am a 41 year old mom back in college and they didn’t have these fancy calculators when I was in school, so thank you, now maybe I won’t look stupid needing help to do a calculation.
