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 231,062,125, 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 | 231,062,125 | |
| -1 | -231,062,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,062,125.
Example:
1 x 231,062,125 = 231,062,125
and
-1 x -231,062,125 = 231,062,125
Notice both answers equal 231,062,125
With that explanation out of the way, let's continue. Next, we take the number 231,062,125 and divide it by 2:
231,062,125 ÷ 2 = 115,531,062.5
If the quotient is a whole number, then 2 and 115,531,062.5 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 | 231,062,125 | |
| -1 | -231,062,125 |
Now, we try dividing 231,062,125 by 3:
231,062,125 ÷ 3 = 77,020,708.3333
If the quotient is a whole number, then 3 and 77,020,708.3333 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 | 231,062,125 | |
| -1 | -231,062,125 |
Let's try dividing by 4:
231,062,125 ÷ 4 = 57,765,531.25
If the quotient is a whole number, then 4 and 57,765,531.25 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 | 231,062,125 | |
| -1 | 231,062,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 264,071 | 1,320,355 | 1,848,497 | 6,601,775 | 9,242,485 | 33,008,875 | 46,212,425 | 231,062,125 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -264,071 | -1,320,355 | -1,848,497 | -6,601,775 | -9,242,485 | -33,008,875 | -46,212,425 | -231,062,125 |
