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 231,936,859, 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 | 231,936,859 | |
| -1 | -231,936,859 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,936,859.
Example:
1 x 231,936,859 = 231,936,859
and
-1 x -231,936,859 = 231,936,859
Notice both answers equal 231,936,859
With that explanation out of the way, let's continue. Next, we take the number 231,936,859 and divide it by 2:
231,936,859 ÷ 2 = 115,968,429.5
If the quotient is a whole number, then 2 and 115,968,429.5 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 | 231,936,859 | |
| -1 | -231,936,859 |
Now, we try dividing 231,936,859 by 3:
231,936,859 ÷ 3 = 77,312,286.3333
If the quotient is a whole number, then 3 and 77,312,286.3333 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 | 231,936,859 | |
| -1 | -231,936,859 |
Let's try dividing by 4:
231,936,859 ÷ 4 = 57,984,214.75
If the quotient is a whole number, then 4 and 57,984,214.75 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 | 231,936,859 | |
| -1 | 231,936,859 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 1,151 | 2,617 | 8,057 | 12,661 | 18,319 | 28,787 | 88,627 | 201,509 | 3,012,167 | 21,085,169 | 33,133,837 | 231,936,859 |
| -1 | -7 | -11 | -77 | -1,151 | -2,617 | -8,057 | -12,661 | -18,319 | -28,787 | -88,627 | -201,509 | -3,012,167 | -21,085,169 | -33,133,837 | -231,936,859 |
