GCD and LCM - Using Classwiz

Use Casio fx-991EX Classwiz to solve and analyse GCD and LCM!

[@MrNehygienix]

Thanks, although this is only a guide to prime factorization - one needs to calculate GCD and LCM from those primes. GCD by multiplying all primes occurring in both numbers, and LCM by formula LCM = (a*b)/GCD.

You dont need it because the international version of the 991 ex lacks of these basic functions..... so.....

Where In the world is 2,4,4 and 8?

[@yo6493]

4 and 8 arent prime

[@lutfulbasharrobin877]

Your LCM result is wrong. LCM of 36,48,34 = 2*2*4*9*17=2448

This is not true. Casio 991 ex does NOT Have lcm, Gcd andH other functions. At least, US version, EU version do NOT have this basic, elementary function, Only Germany, who knows why, blessed by God, they have these so basic functions. I am really upset. I luckily discovered this bias just a moment before buying it... the "best calculator" is worst than the American Market 2011 fx-112 es plus second edition.

They made it for US have to strain their brains and be a little smarter than Germans :))

yes

[@md.asadchowdhurydipu2634]

Fx991dex can do LCM and GCD

[@MrMarcec85]

@@md.asadchowdhurydipu2634 dex not ex. And dex is only in German and sold in Germany, or exported at a crazy price.

[@whitevinegar4168]

At least you guys have 115 es plus, which is not available here in India officially. India, Pakistan and Bangladesh don't get these basic function

what are you saying😂😂😂😂
