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 231,123,235, 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 | 231,123,235 | |
| -1 | -231,123,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,123,235.
Example:
1 x 231,123,235 = 231,123,235
and
-1 x -231,123,235 = 231,123,235
Notice both answers equal 231,123,235
With that explanation out of the way, let's continue. Next, we take the number 231,123,235 and divide it by 2:
231,123,235 ÷ 2 = 115,561,617.5
If the quotient is a whole number, then 2 and 115,561,617.5 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 | 231,123,235 | |
| -1 | -231,123,235 |
Now, we try dividing 231,123,235 by 3:
231,123,235 ÷ 3 = 77,041,078.3333
If the quotient is a whole number, then 3 and 77,041,078.3333 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 | 231,123,235 | |
| -1 | -231,123,235 |
Let's try dividing by 4:
231,123,235 ÷ 4 = 57,780,808.75
If the quotient is a whole number, then 4 and 57,780,808.75 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 | 231,123,235 | |
| -1 | 231,123,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,129 | 5,645 | 5,849 | 7,903 | 29,245 | 39,515 | 40,943 | 204,715 | 6,603,521 | 33,017,605 | 46,224,647 | 231,123,235 |
| -1 | -5 | -7 | -35 | -1,129 | -5,645 | -5,849 | -7,903 | -29,245 | -39,515 | -40,943 | -204,715 | -6,603,521 | -33,017,605 | -46,224,647 | -231,123,235 |
