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 231,004,333, 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 | 231,004,333 | |
| -1 | -231,004,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,004,333.
Example:
1 x 231,004,333 = 231,004,333
and
-1 x -231,004,333 = 231,004,333
Notice both answers equal 231,004,333
With that explanation out of the way, let's continue. Next, we take the number 231,004,333 and divide it by 2:
231,004,333 ÷ 2 = 115,502,166.5
If the quotient is a whole number, then 2 and 115,502,166.5 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 | 231,004,333 | |
| -1 | -231,004,333 |
Now, we try dividing 231,004,333 by 3:
231,004,333 ÷ 3 = 77,001,444.3333
If the quotient is a whole number, then 3 and 77,001,444.3333 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 | 231,004,333 | |
| -1 | -231,004,333 |
Let's try dividing by 4:
231,004,333 ÷ 4 = 57,751,083.25
If the quotient is a whole number, then 4 and 57,751,083.25 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 | 231,004,333 | |
| -1 | 231,004,333 |
If you did it right, you will end up with this table:
| 1 | 7 | 107 | 179 | 749 | 1,253 | 1,723 | 12,061 | 19,153 | 134,071 | 184,361 | 308,417 | 1,290,527 | 2,158,919 | 33,000,619 | 231,004,333 |
| -1 | -7 | -107 | -179 | -749 | -1,253 | -1,723 | -12,061 | -19,153 | -134,071 | -184,361 | -308,417 | -1,290,527 | -2,158,919 | -33,000,619 | -231,004,333 |
