Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 173,231,255, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 173,231,255 | |
| -1 | -173,231,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 173,231,255.
Example:
1 x 173,231,255 = 173,231,255
and
-1 x -173,231,255 = 173,231,255
Notice both answers equal 173,231,255
With that explanation out of the way, let's continue. Next, we take the number 173,231,255 and divide it by 2:
173,231,255 ÷ 2 = 86,615,627.5
If the quotient is a whole number, then 2 and 86,615,627.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 173,231,255 | |
| -1 | -173,231,255 |
Now, we try dividing 173,231,255 by 3:
173,231,255 ÷ 3 = 57,743,751.6667
If the quotient is a whole number, then 3 and 57,743,751.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 173,231,255 | |
| -1 | -173,231,255 |
Let's try dividing by 4:
173,231,255 ÷ 4 = 43,307,813.75
If the quotient is a whole number, then 4 and 43,307,813.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 173,231,255 | |
| -1 | 173,231,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 971 | 1,151 | 4,855 | 5,755 | 30,101 | 35,681 | 150,505 | 178,405 | 1,117,621 | 5,588,105 | 34,646,251 | 173,231,255 |
| -1 | -5 | -31 | -155 | -971 | -1,151 | -4,855 | -5,755 | -30,101 | -35,681 | -150,505 | -178,405 | -1,117,621 | -5,588,105 | -34,646,251 | -173,231,255 |
