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 231,227,125, 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 | 231,227,125 | |
| -1 | -231,227,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,227,125.
Example:
1 x 231,227,125 = 231,227,125
and
-1 x -231,227,125 = 231,227,125
Notice both answers equal 231,227,125
With that explanation out of the way, let's continue. Next, we take the number 231,227,125 and divide it by 2:
231,227,125 ÷ 2 = 115,613,562.5
If the quotient is a whole number, then 2 and 115,613,562.5 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 | 231,227,125 | |
| -1 | -231,227,125 |
Now, we try dividing 231,227,125 by 3:
231,227,125 ÷ 3 = 77,075,708.3333
If the quotient is a whole number, then 3 and 77,075,708.3333 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 | 231,227,125 | |
| -1 | -231,227,125 |
Let's try dividing by 4:
231,227,125 ÷ 4 = 57,806,781.25
If the quotient is a whole number, then 4 and 57,806,781.25 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 | 231,227,125 | |
| -1 | 231,227,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 125 | 215 | 1,075 | 5,375 | 43,019 | 215,095 | 1,075,475 | 1,849,817 | 5,377,375 | 9,249,085 | 46,245,425 | 231,227,125 |
| -1 | -5 | -25 | -43 | -125 | -215 | -1,075 | -5,375 | -43,019 | -215,095 | -1,075,475 | -1,849,817 | -5,377,375 | -9,249,085 | -46,245,425 | -231,227,125 |
