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 231,043,403, 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 | 231,043,403 | |
| -1 | -231,043,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,043,403.
Example:
1 x 231,043,403 = 231,043,403
and
-1 x -231,043,403 = 231,043,403
Notice both answers equal 231,043,403
With that explanation out of the way, let's continue. Next, we take the number 231,043,403 and divide it by 2:
231,043,403 ÷ 2 = 115,521,701.5
If the quotient is a whole number, then 2 and 115,521,701.5 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 | 231,043,403 | |
| -1 | -231,043,403 |
Now, we try dividing 231,043,403 by 3:
231,043,403 ÷ 3 = 77,014,467.6667
If the quotient is a whole number, then 3 and 77,014,467.6667 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 | 231,043,403 | |
| -1 | -231,043,403 |
Let's try dividing by 4:
231,043,403 ÷ 4 = 57,760,850.75
If the quotient is a whole number, then 4 and 57,760,850.75 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 | 231,043,403 | |
| -1 | 231,043,403 |
If you did it right, you will end up with this table:
| 1 | 31 | 67 | 173 | 643 | 2,077 | 5,363 | 11,591 | 19,933 | 43,081 | 111,239 | 359,321 | 1,335,511 | 3,448,409 | 7,453,013 | 231,043,403 |
| -1 | -31 | -67 | -173 | -643 | -2,077 | -5,363 | -11,591 | -19,933 | -43,081 | -111,239 | -359,321 | -1,335,511 | -3,448,409 | -7,453,013 | -231,043,403 |
