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.

- Decompose the first number in prime factors. If a prime factor is repeated use the exponent notation:
**That helps.** **D**ecompose 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 decompositions**it must be in the HCD /HCF, with the smallest of its two exponents. - Do that for all prime factors

(2^5)*3*

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

2^3, 5^4, 7, 11

The highest common divisor/Highest common factor is

Hi,

A 6ya expert can help you resolve that issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

Good luck!

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

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

SOURCE: i can't find the EXP button on my Casio fx-83GT

Your question is slightly ambiguous.

If you refer to the exponential function (power to base e = 2,7182818...), the key sequence is [SHIFT] [ln]. (rightmost button column, two rows below the ON key).

If you refer to a key allowing to enter powers of 10, like in 3,14 x 10²³, see the button labeled

its located in the bottom button row, center column.

SOURCE: I have a casio fx-83gt

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

SOURCE: i have a fx-83GT PLUS

To get to the general computational mode, press MODE and select 1:COMP.

To change the number display mode to another one, Press SHIFT MODE to enter SetUp. Select NORM or Sci for scientific mode.

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**

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.

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.

Press [SHIFT][MODE][6][4]:

When you select FIX (by pressing [SHIFT][MODE][6] ) on your calculator you can specify number of decimal places which are displayed (you can choose any number from 0 to 9).
