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 231,010,439, 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 | 231,010,439 | |
| -1 | -231,010,439 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,010,439.
Example:
1 x 231,010,439 = 231,010,439
and
-1 x -231,010,439 = 231,010,439
Notice both answers equal 231,010,439
With that explanation out of the way, let's continue. Next, we take the number 231,010,439 and divide it by 2:
231,010,439 ÷ 2 = 115,505,219.5
If the quotient is a whole number, then 2 and 115,505,219.5 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 | 231,010,439 | |
| -1 | -231,010,439 |
Now, we try dividing 231,010,439 by 3:
231,010,439 ÷ 3 = 77,003,479.6667
If the quotient is a whole number, then 3 and 77,003,479.6667 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 | 231,010,439 | |
| -1 | -231,010,439 |
Let's try dividing by 4:
231,010,439 ÷ 4 = 57,752,609.75
If the quotient is a whole number, then 4 and 57,752,609.75 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 | 231,010,439 | |
| -1 | 231,010,439 |
If you did it right, you will end up with this table:
| 1 | 11 | 67 | 307 | 737 | 1,021 | 3,377 | 11,231 | 20,569 | 68,407 | 226,259 | 313,447 | 752,477 | 3,447,917 | 21,000,949 | 231,010,439 |
| -1 | -11 | -67 | -307 | -737 | -1,021 | -3,377 | -11,231 | -20,569 | -68,407 | -226,259 | -313,447 | -752,477 | -3,447,917 | -21,000,949 | -231,010,439 |
