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 231,765,331, 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 | 231,765,331 | |
| -1 | -231,765,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,765,331.
Example:
1 x 231,765,331 = 231,765,331
and
-1 x -231,765,331 = 231,765,331
Notice both answers equal 231,765,331
With that explanation out of the way, let's continue. Next, we take the number 231,765,331 and divide it by 2:
231,765,331 ÷ 2 = 115,882,665.5
If the quotient is a whole number, then 2 and 115,882,665.5 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 | 231,765,331 | |
| -1 | -231,765,331 |
Now, we try dividing 231,765,331 by 3:
231,765,331 ÷ 3 = 77,255,110.3333
If the quotient is a whole number, then 3 and 77,255,110.3333 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 | 231,765,331 | |
| -1 | -231,765,331 |
Let's try dividing by 4:
231,765,331 ÷ 4 = 57,941,332.75
If the quotient is a whole number, then 4 and 57,941,332.75 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 | 231,765,331 | |
| -1 | 231,765,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 131 | 217 | 263 | 917 | 961 | 1,841 | 4,061 | 6,727 | 8,153 | 28,427 | 34,453 | 57,071 | 125,891 | 241,171 | 252,743 | 881,237 | 1,068,043 | 1,769,201 | 7,476,301 | 33,109,333 | 231,765,331 |
| -1 | -7 | -31 | -131 | -217 | -263 | -917 | -961 | -1,841 | -4,061 | -6,727 | -8,153 | -28,427 | -34,453 | -57,071 | -125,891 | -241,171 | -252,743 | -881,237 | -1,068,043 | -1,769,201 | -7,476,301 | -33,109,333 | -231,765,331 |
