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 230,323,115, 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 | 230,323,115 | |
| -1 | -230,323,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,323,115.
Example:
1 x 230,323,115 = 230,323,115
and
-1 x -230,323,115 = 230,323,115
Notice both answers equal 230,323,115
With that explanation out of the way, let's continue. Next, we take the number 230,323,115 and divide it by 2:
230,323,115 ÷ 2 = 115,161,557.5
If the quotient is a whole number, then 2 and 115,161,557.5 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 | 230,323,115 | |
| -1 | -230,323,115 |
Now, we try dividing 230,323,115 by 3:
230,323,115 ÷ 3 = 76,774,371.6667
If the quotient is a whole number, then 3 and 76,774,371.6667 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 | 230,323,115 | |
| -1 | -230,323,115 |
Let's try dividing by 4:
230,323,115 ÷ 4 = 57,580,778.75
If the quotient is a whole number, then 4 and 57,580,778.75 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 | 230,323,115 | |
| -1 | 230,323,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 607 | 3,035 | 6,677 | 6,899 | 33,385 | 34,495 | 75,889 | 379,445 | 4,187,693 | 20,938,465 | 46,064,623 | 230,323,115 |
| -1 | -5 | -11 | -55 | -607 | -3,035 | -6,677 | -6,899 | -33,385 | -34,495 | -75,889 | -379,445 | -4,187,693 | -20,938,465 | -46,064,623 | -230,323,115 |
