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 231,060,197, 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 | 231,060,197 | |
| -1 | -231,060,197 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,060,197.
Example:
1 x 231,060,197 = 231,060,197
and
-1 x -231,060,197 = 231,060,197
Notice both answers equal 231,060,197
With that explanation out of the way, let's continue. Next, we take the number 231,060,197 and divide it by 2:
231,060,197 ÷ 2 = 115,530,098.5
If the quotient is a whole number, then 2 and 115,530,098.5 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 | 231,060,197 | |
| -1 | -231,060,197 |
Now, we try dividing 231,060,197 by 3:
231,060,197 ÷ 3 = 77,020,065.6667
If the quotient is a whole number, then 3 and 77,020,065.6667 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 | 231,060,197 | |
| -1 | -231,060,197 |
Let's try dividing by 4:
231,060,197 ÷ 4 = 57,765,049.25
If the quotient is a whole number, then 4 and 57,765,049.25 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 | 231,060,197 | |
| -1 | 231,060,197 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 157 | 551 | 2,671 | 2,983 | 4,553 | 50,749 | 77,459 | 86,507 | 419,347 | 1,471,721 | 7,967,593 | 12,161,063 | 231,060,197 |
| -1 | -19 | -29 | -157 | -551 | -2,671 | -2,983 | -4,553 | -50,749 | -77,459 | -86,507 | -419,347 | -1,471,721 | -7,967,593 | -12,161,063 | -231,060,197 |
