Hello,

I'm an old owner of the Casio fx-570ES and I'm still satisfied by it overall especially for it's "natural display" capabilities. I'd like to know if there's any model which has the same great features as this one plus it can compute for me the following operations:

1) The LCM and GCD of any numbers.
2) The Prime factorization of any number

Thanks

You should buy a programmable calculator and write these three functions yourself.

Many thanks for your reply, I didn't know that I have to go with a programmable one. Could you plz inform me about a good model that can accomodate many programs and how can I write functions like the LCM/GCD myself if I'm not a programmer? Is there any ready-made functions that I can download into the calculator or something?

Think about buying a fx9750G, it's cheap and you can upgrade it into a fx9860G

I only know about the fx9860G - models. You can program it in CasioBasic (easy to learn) or in C (fast).
I could make you the programs, that's not the problem.

FYI, fx9750, 9860, and prizm can do it by OPTN' /> F6' /> F4' /> (NUM) F6' /> then press F2' /> (GCD) or F3' /> (LCM)

Cool! I didn't know about this. Thanks!

No Problem

Hello magoood and welcome to UCF! You should introduce yourself.

Thanks for your input but I wished if the calculator is a one that is natural display and affordable, hopefully.

The 9860 has. Costs: about 100€

The 9860 has. Costs: about 100€

You can buy it for less if you go on ebay/craigslist. I got mine for $40 (30€).

[naib864]

Mine had cost ca. 120$ (90€)

The new powergraphic2 calcs are more expensive.

[naib864]

Then I've got a cheap power graphic 2.

The school can buy lots of calcs at once, and then they can buy it cheaper. So mine costed 87€.

[naib864]

Thats right. My calc is buying by my school.

I got my fx9750 at office max on clearance for $38/28€
