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 231,113,443, 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 | 231,113,443 | |
| -1 | -231,113,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,113,443.
Example:
1 x 231,113,443 = 231,113,443
and
-1 x -231,113,443 = 231,113,443
Notice both answers equal 231,113,443
With that explanation out of the way, let's continue. Next, we take the number 231,113,443 and divide it by 2:
231,113,443 ÷ 2 = 115,556,721.5
If the quotient is a whole number, then 2 and 115,556,721.5 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 | 231,113,443 | |
| -1 | -231,113,443 |
Now, we try dividing 231,113,443 by 3:
231,113,443 ÷ 3 = 77,037,814.3333
If the quotient is a whole number, then 3 and 77,037,814.3333 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 | 231,113,443 | |
| -1 | -231,113,443 |
Let's try dividing by 4:
231,113,443 ÷ 4 = 57,778,360.75
If the quotient is a whole number, then 4 and 57,778,360.75 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 | 231,113,443 | |
| -1 | 231,113,443 |
If you did it right, you will end up with this table:
| 1 | 11 | 53 | 59 | 583 | 649 | 3,127 | 6,719 | 34,397 | 73,909 | 356,107 | 396,421 | 3,917,177 | 4,360,631 | 21,010,313 | 231,113,443 |
| -1 | -11 | -53 | -59 | -583 | -649 | -3,127 | -6,719 | -34,397 | -73,909 | -356,107 | -396,421 | -3,917,177 | -4,360,631 | -21,010,313 | -231,113,443 |
