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 231,014,203, 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 | 231,014,203 | |
| -1 | -231,014,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,014,203.
Example:
1 x 231,014,203 = 231,014,203
and
-1 x -231,014,203 = 231,014,203
Notice both answers equal 231,014,203
With that explanation out of the way, let's continue. Next, we take the number 231,014,203 and divide it by 2:
231,014,203 ÷ 2 = 115,507,101.5
If the quotient is a whole number, then 2 and 115,507,101.5 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 | 231,014,203 | |
| -1 | -231,014,203 |
Now, we try dividing 231,014,203 by 3:
231,014,203 ÷ 3 = 77,004,734.3333
If the quotient is a whole number, then 3 and 77,004,734.3333 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 | 231,014,203 | |
| -1 | -231,014,203 |
Let's try dividing by 4:
231,014,203 ÷ 4 = 57,753,550.75
If the quotient is a whole number, then 4 and 57,753,550.75 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 | 231,014,203 | |
| -1 | 231,014,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 263 | 1,841 | 4,327 | 7,627 | 30,289 | 53,389 | 125,483 | 878,381 | 1,138,001 | 7,966,007 | 33,002,029 | 231,014,203 |
| -1 | -7 | -29 | -203 | -263 | -1,841 | -4,327 | -7,627 | -30,289 | -53,389 | -125,483 | -878,381 | -1,138,001 | -7,966,007 | -33,002,029 | -231,014,203 |
