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 231,218,273, 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 | 231,218,273 | |
| -1 | -231,218,273 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,218,273.
Example:
1 x 231,218,273 = 231,218,273
and
-1 x -231,218,273 = 231,218,273
Notice both answers equal 231,218,273
With that explanation out of the way, let's continue. Next, we take the number 231,218,273 and divide it by 2:
231,218,273 ÷ 2 = 115,609,136.5
If the quotient is a whole number, then 2 and 115,609,136.5 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 | 231,218,273 | |
| -1 | -231,218,273 |
Now, we try dividing 231,218,273 by 3:
231,218,273 ÷ 3 = 77,072,757.6667
If the quotient is a whole number, then 3 and 77,072,757.6667 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 | 231,218,273 | |
| -1 | -231,218,273 |
Let's try dividing by 4:
231,218,273 ÷ 4 = 57,804,568.25
If the quotient is a whole number, then 4 and 57,804,568.25 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 | 231,218,273 | |
| -1 | 231,218,273 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 67 | 143 | 737 | 871 | 9,581 | 24,133 | 265,463 | 313,729 | 1,616,911 | 3,451,019 | 17,786,021 | 21,019,843 | 231,218,273 |
| -1 | -11 | -13 | -67 | -143 | -737 | -871 | -9,581 | -24,133 | -265,463 | -313,729 | -1,616,911 | -3,451,019 | -17,786,021 | -21,019,843 | -231,218,273 |
