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 230,013,005, 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 | 230,013,005 | |
| -1 | -230,013,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,013,005.
Example:
1 x 230,013,005 = 230,013,005
and
-1 x -230,013,005 = 230,013,005
Notice both answers equal 230,013,005
With that explanation out of the way, let's continue. Next, we take the number 230,013,005 and divide it by 2:
230,013,005 ÷ 2 = 115,006,502.5
If the quotient is a whole number, then 2 and 115,006,502.5 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 | 230,013,005 | |
| -1 | -230,013,005 |
Now, we try dividing 230,013,005 by 3:
230,013,005 ÷ 3 = 76,671,001.6667
If the quotient is a whole number, then 3 and 76,671,001.6667 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 | 230,013,005 | |
| -1 | -230,013,005 |
Let's try dividing by 4:
230,013,005 ÷ 4 = 57,503,251.25
If the quotient is a whole number, then 4 and 57,503,251.25 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 | 230,013,005 | |
| -1 | 230,013,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 305 | 599 | 1,259 | 2,995 | 6,295 | 36,539 | 76,799 | 182,695 | 383,995 | 754,141 | 3,770,705 | 46,002,601 | 230,013,005 |
| -1 | -5 | -61 | -305 | -599 | -1,259 | -2,995 | -6,295 | -36,539 | -76,799 | -182,695 | -383,995 | -754,141 | -3,770,705 | -46,002,601 | -230,013,005 |
