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 123,200,231, 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 | 123,200,231 | |
| -1 | -123,200,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 123,200,231.
Example:
1 x 123,200,231 = 123,200,231
and
-1 x -123,200,231 = 123,200,231
Notice both answers equal 123,200,231
With that explanation out of the way, let's continue. Next, we take the number 123,200,231 and divide it by 2:
123,200,231 ÷ 2 = 61,600,115.5
If the quotient is a whole number, then 2 and 61,600,115.5 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 | 123,200,231 | |
| -1 | -123,200,231 |
Now, we try dividing 123,200,231 by 3:
123,200,231 ÷ 3 = 41,066,743.6667
If the quotient is a whole number, then 3 and 41,066,743.6667 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 | 123,200,231 | |
| -1 | -123,200,231 |
Let's try dividing by 4:
123,200,231 ÷ 4 = 30,800,057.75
If the quotient is a whole number, then 4 and 30,800,057.75 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 | 123,200,231 | |
| -1 | 123,200,231 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 31 | 77 | 217 | 341 | 2,387 | 51,613 | 361,291 | 567,743 | 1,600,003 | 3,974,201 | 11,200,021 | 17,600,033 | 123,200,231 |
| -1 | -7 | -11 | -31 | -77 | -217 | -341 | -2,387 | -51,613 | -361,291 | -567,743 | -1,600,003 | -3,974,201 | -11,200,021 | -17,600,033 | -123,200,231 |
