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 231,402,335, 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 | 231,402,335 | |
| -1 | -231,402,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,402,335.
Example:
1 x 231,402,335 = 231,402,335
and
-1 x -231,402,335 = 231,402,335
Notice both answers equal 231,402,335
With that explanation out of the way, let's continue. Next, we take the number 231,402,335 and divide it by 2:
231,402,335 ÷ 2 = 115,701,167.5
If the quotient is a whole number, then 2 and 115,701,167.5 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 | 231,402,335 | |
| -1 | -231,402,335 |
Now, we try dividing 231,402,335 by 3:
231,402,335 ÷ 3 = 77,134,111.6667
If the quotient is a whole number, then 3 and 77,134,111.6667 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 | 231,402,335 | |
| -1 | -231,402,335 |
Let's try dividing by 4:
231,402,335 ÷ 4 = 57,850,583.75
If the quotient is a whole number, then 4 and 57,850,583.75 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 | 231,402,335 | |
| -1 | 231,402,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 139 | 365 | 695 | 4,561 | 10,147 | 22,805 | 50,735 | 332,953 | 633,979 | 1,664,765 | 3,169,895 | 46,280,467 | 231,402,335 |
| -1 | -5 | -73 | -139 | -365 | -695 | -4,561 | -10,147 | -22,805 | -50,735 | -332,953 | -633,979 | -1,664,765 | -3,169,895 | -46,280,467 | -231,402,335 |
