242/6 Need the breakdown of this division, on calculator gave 40,3 By hand 4,3 Can someone help me on this

This calculator does not have a key that you can use to find the prime factor of an integer.
You can however use the calculator to find the factors
1. If number is even divide it by 2
Keep dividing by 2, while keeping track of how many times you divided by 2.
If you divided 5 times by 2 before getting an odd number, then your first factor is 2^5
2. Now try dividing by 3, keep track of the number of times you divided by 3 before you could not divide by 3 any more. If you divided 0 times by 3, your second factor is 3^0, or 1 and 3 is not a factor.
If you divided 4 times by 3, your second factor is 3^4
3. Divide by 5, until you can't any more. Keep track of the number of times you divided by 5.
4. Divide by all other prime numbers 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, etc. For each prime number, keep track of how many times you divided by it, until you could not any more.

Example: 23100
Division by 2
23100/2=11550 ---------> 1 division by 2
11550/2=5775 ----------> 2 divisions by 2
Note that 5775 is not divisible by 2. No more divisions by 2.
First factor is 2^2

Division by 3:
5775/3=1925 ----------> 1 division by 3
1925/3=641. 66667 Not an integer. No more divisions by 3.
2nd factor is 3^1

Division by 5 (number ends in 5)
1925/5 =385 -------> 1 division by 5
385/5=77 ----------> 2 divisions by 5 and no more (quotient does not end in 0 or 5)
3rd factor is 5^2

Division by 7
77/7=11 --------> 1 division by 7, and no more
4th factor is 7^1=7

Division by 11
11/11=1
5th factor is 11^1=11

Assembling the factors 2^2, 3^1, 5^2, 7, 11
Prime factorization of 23100 is
23100=(2^2)(3)(5^2)(7)11

Withe a calculator, all you have to do is turn the calculator ON, key in the number 2072, press the division key, key in the denominator 4549 and press the = or EXE keys. The result should be about 0.455
By hand you will have to perform a long division.

Unless you are meaning something more specific, ratios are calculated through simple division. For example if there are 2 oranges and 4 apples, the ratio of oranges to apples is 2:4, and the ratio of oranges to the total number of pieces of fruit is 2:6. These ratios can also be expressed in fraction form: there are 2/4 as many oranges as apples, and 2/6 of the pieces of fruit are oranges. If necessary you can perform the calculation 2/4 = 2 therefore there are .5 (half) as many oranges as apples and 2/6 = 0.33333333333333 therefore approximately .333 pieces of fruit are oranges.


On your calculator you should simply need to use the division button to accomplish this.

Because 242 divided by 6 = 40.33333333

242/6=40.3333333

What are you trying to do anyway? Ratio? Or division?

The calculator's memory is limited. The largest number it can handle is about 10^100 and that is a bit more then 69!

It you are trying to calculate the permutation and/or combinations, which involve the ratios of factorials nPr=n!/(n-r)! and nCr= n!/((n-r)!r!) you will have better luck using the relevant commands directly and not use the above divisions.

When you are calculating ratios by hand (why would you do that? you might ask) there is a simple trick you can take advantage of. It involves expanding the factorial in the numerator as in the following example:
Calculate 7!/4!=7*6*5*4!/4!=7*6*5=210.

Unless your calculator is wrong the answer is 8. but I think you wanted to ask that the calculator gave wrong results. If so remove and clean the pads, warm off the pads, clean battery contacts and reset.

How to do constant multiplication or division on the Canon P170-DH calculator

This process actually requires fewer keystrokes than other calculators. Basically, just do the first problem
and then do the next items with just the next number and the EQUAL key. For example,

*** Constant Multiplication ***
2 (multiply key)
10 (= key)
(The answer 20 shows on the screen. Note, the 2 is still stored as a constant without doing anything, just continue)
4 = (shows the answer 8 on the screen)
20 = (shows the answer 40 on the screen)
100 = (shows the answer 200 on the screen)

*** Constant Division ***
10 (divided by key)
2 =
(shows the answer 5 on the screen, the 2 is still stored as a constant without doing anything, just continue)
100 = (shows the answer 50 on the screen)
500 = (shows the answer 250 on the screen)
4 = (shows the answer 2 on the screen)

This is a really good site to learn about repairing amps and anything else you want to know about car audio. Are you wanting to replace the board or looking for someone to repair your amp.?

You just use the division button and it helps if you put the fraction in parenthese. So if you were trying to put in 1/4 you would enter 1 then the division button then 4. Voila!
