Question about Casio Office Equipment & Supplies

I don't know how to do the HCF on a casio calculator fx-83GT PLUS and I would like to know the simplest way to do so

The calculator has no application that will find the highest common divisor (or HCF) but that should not be difficult to do by hand.

Decompose the first number in prime factors. If a prime factor is repeated use the exponent notation: **That helps**

Decompose the second number in prime factors too, using the exponent notation.

Now look at the two decompositions. If a prime factor is present in both decomposition it must be in the HCD /HCF, with the smallest of the two exponents. Do that for all prime factors

Example;

(2^5)*3***(5^4)**(7^3)***11**

**(2^3)***(5^6)*(11^2)***7**

The prime factors that are present in both decompositions are

2, 5, 7, and 11

From the two decompositions select the smallest power of each

2^3, 5^4, 7, 11

The highest common divisor/Highest common factor is

**(2^3)*(5^4)*7*11**

SOURCE: Factoring polynomials "Algebra"

Mode>choose "5"

choose equation format "4"

input the coefficient for a which is "1" and hit "="

input the coefficient for b which is "4" and hit "="

input the coefficient for c which is "3" and hit "="

input the coefficient for d which is "12" and hit "="

Hit "=" for X1

Hit "=" again for X2

Hit "=" again for X3

Unless I am failing to understand your problem, just combine like terms to get:

9x^2+2x+4 and then enter those coefficients into the quadratic solver.

That will get you the two answers -- both of them will be complex.

If you wanted to turn those two answers into factors (complex) of the original equation simply

change the signs on each and put an x in front.

Of course, the quadratic formula would also work.

SOURCE: is there any way to stop the casio fx-83GT plus

Yes. Press SHIFT MODE 2 to select the LineIO mode.

The computational mode of your calculator is set to VERIFY. Change it to the general COMPUTATIONAL mode. Press MODE 1 (COMP).

There is nothing you can do to make the calculator find the HCF for you. No point complaining about that. But if you are interested in doing it by hand (using the calculator to do the divisions for you) here how it is done.

**Example: **Here are the decompositions of two numbers

(2^5)*3***(5^4)**(7^3)***11** and **(2^3)***(5^6)*(11^2)***7**

The prime factors that are present in both decompositions are

2, 5, 7, and 11

From the two decompositions select the smallest power of each common prime factor. They are represented in** bold font**s.

2^3, 5^4, 7, 11

The highest common divisor/Highest common factor is

**(2^3)*(5^4)*7*11**

You should try to explore the calculator to find its capabilities. You can also read the manual. Everything is in it.

Press the Mode button, then the down arrow key. On the second page of the mode list you find**2:Verif**

Sorry, no.

Sorry to be the carrier of bad news but the Casio FX-83 GT Plus does not
have a baseN calculation mode. You cannot do any arithmetic in binary,
octal or hexadecimal numeration.

I do not think that Casio scientific calculators have the possibility to separate thousands, millions etc. The Sharp have that feature.

Like many other Casio calculators, the fx-83GT Plus doesn't provide the modulus function. You have to do it the hard way.

To calculate 19 MOD 10 (which is 9, not 10 as you state in your question), first divide 19 by 10 and note the integer portion of the result (in this case, 1). Then subtract from 19 the product of 10 and the result of the first step. The result of the subtraction is the modulus. 19 - (1*10) = 9.

Are you using the right type of logarithms? The calculator provides for two types: common (base 10) and natural (base e).

Could you post an example or two, with the answers you get and the expected answers?

I have a fx-570ES plus instead but one easy way I found to calculate the LCM us by adding 2 fractions in the following format: 1/a + 1/b, where a and b are the numbers you are calculating the LCM for. In my calculator the result is displayed as a fraction, with the denominator being the LCM. From there I can also figure out the HCF with the following formula: HCF=(a * b) / LCM. In some calculators the fraction might get displayed in decimal format but most of the newer ones can switch between fraction and decimal format.
I hope this helps.

There is only one key to toggle between display formats: the S<>D key. Pressing the key repeatedly will cycle through all available display formats.
