The prime factors are 2, 3, and 5. If you include the non-prime factors, you also have 1, 6, 10, 15, and 30.

What Are The Advantages Of Factoring?


Big companies increasingly stretch invoice payment from 30 days to 90 days or longer. This puts small operations in a bind because their employee salaries, vendor payments, and taxes are due whether the customer pays or not. The solution for many businesses is factoring. Sell your accounts receivable at a discount and get immediately paid. You get the cash flow you require to meet current working expenses without incurring debt.

Is it possible to calculate factors using a TI-30x IIS


I believe factors can be calculated on any basic calculator.

Starting with 1, increasing by 1 until you get to square root (number) + 1

Let's do an example.

28
square root (28)+1 = 6
Factors
1, 28/1=28
2, 28/2=14 14*2 - 28 = 0 (when you divide, you get no decimal)
3, 28/3=9.33333 - not a factor - doesn't go in evenly
4, 28/4 =7
5, 28/5=5.6 - not a factor - doesn't go in evenly
6, 28/6=4.66666 - not a factor
So now we can list our factors - 1, 28, 2, 14, 4, 7
Putting them in order, we get 1, 2, 4, 7, 14 and 28.

Good luck,

Paul

How do I get all the factors of a constant using my calculator?


There is a program on page 253 of the manual (http://support.casio.com/manualfile.php?rgn=5&cid=004002013) to get the prime factors of any number. You could modify the program to get all the factors.

Another way would be to do it manually. I start with the number 1 and go up to the square root of the number. The square root of 120 is 10.95, so let's go up to 11. Using 120 as an example:

120 /1 = 120 thus factor is (1, 120)
120/2 = 60 thus factor is (2, 60)
120/3 = 40 thus factor is (3, 40)
120/4 = 30 thus factor is (4, 30)
120/5 = 24 thus factor is (5, 24)
120/6 = 20 thus factor is (6, 20)
120/7 = 1.7 thus 7 not a factor
120/8 = 15 thus factor is (8,15)
120/9 = 13.3 thus 9 is not a factor
120/10 = 12 thus factor is (10,12)
120/11 = 10.9 thus 11 is not a factor.

Good luck.

How to find G.C.F. on a TI-30xIIs calculator?


I don't think there's specific key for this but you can do it this way:

  1. Divide those 2 numbers for which you want to find gcf
  2. If you get result as decimal number press keys [2nd][PRB] to display it as fraction
  3. Also if fraction you get is in form a b/c (ex. 1 2/3) you have to convert it to form d/c (for 1 2/3 that would be 5/3)
  4. Greatest common factor is then 1st number divided by numerator (or 2nd number divided by denominator)
For example:
  • You want to find greatest common factor of 30 and 18.
  • You divide them: you should get 5/3 (after converting result to fraction of form d/c, as described in steps 2 and 3).
  • This means that 30/18=5/3=5x/3x (x is gcf here).
  • Now you know that x=30/5=18/3=6 so greatest common factor is 6.

I hope this helps :)

Calculate 28 cot 30


If you remember that by definition cot(theta)=1/tan(theta) your expression can be calculated as 28/tan(30). Use parentheses if necessary to enclose the whole tan(30) factor.
Before calculating any trigonometric function make sure that the angle unit is set correctly. In your case I presume that 30 means 30 degrees. Use the [DRG] key to cycle through the angle units.

Which number under 100 has the most primed factors


Hi johnhboland
Prime numbers are 2,3,5,7,11,13,17,23 .........
Take different combinations from the above list and multiply making sure you don't exceed 100

2x3x5 =30
2x3x7 =42
2x3=11 =66
2x3x13 =78
2x5x7 =70
I would say the answers are 30, 42, 66, 78, and 100 all have 3 prime factors
If repetition of the same factor is allowed:
answers would be 64 and 96 both having 6 prime factors
Have a good day
