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 231,076,373, 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 | 231,076,373 | |
| -1 | -231,076,373 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,076,373.
Example:
1 x 231,076,373 = 231,076,373
and
-1 x -231,076,373 = 231,076,373
Notice both answers equal 231,076,373
With that explanation out of the way, let's continue. Next, we take the number 231,076,373 and divide it by 2:
231,076,373 ÷ 2 = 115,538,186.5
If the quotient is a whole number, then 2 and 115,538,186.5 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 | 231,076,373 | |
| -1 | -231,076,373 |
Now, we try dividing 231,076,373 by 3:
231,076,373 ÷ 3 = 77,025,457.6667
If the quotient is a whole number, then 3 and 77,025,457.6667 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 | 231,076,373 | |
| -1 | -231,076,373 |
Let's try dividing by 4:
231,076,373 ÷ 4 = 57,769,093.25
If the quotient is a whole number, then 4 and 57,769,093.25 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 | 231,076,373 | |
| -1 | 231,076,373 |
If you did it right, you will end up with this table:
| 1 | 11 | 127 | 251 | 659 | 1,397 | 2,761 | 7,249 | 31,877 | 83,693 | 165,409 | 350,647 | 920,623 | 1,819,499 | 21,006,943 | 231,076,373 |
| -1 | -11 | -127 | -251 | -659 | -1,397 | -2,761 | -7,249 | -31,877 | -83,693 | -165,409 | -350,647 | -920,623 | -1,819,499 | -21,006,943 | -231,076,373 |
