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 230,013,133, 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 | 230,013,133 | |
| -1 | -230,013,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,013,133.
Example:
1 x 230,013,133 = 230,013,133
and
-1 x -230,013,133 = 230,013,133
Notice both answers equal 230,013,133
With that explanation out of the way, let's continue. Next, we take the number 230,013,133 and divide it by 2:
230,013,133 ÷ 2 = 115,006,566.5
If the quotient is a whole number, then 2 and 115,006,566.5 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 | 230,013,133 | |
| -1 | -230,013,133 |
Now, we try dividing 230,013,133 by 3:
230,013,133 ÷ 3 = 76,671,044.3333
If the quotient is a whole number, then 3 and 76,671,044.3333 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 | 230,013,133 | |
| -1 | -230,013,133 |
Let's try dividing by 4:
230,013,133 ÷ 4 = 57,503,283.25
If the quotient is a whole number, then 4 and 57,503,283.25 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 | 230,013,133 | |
| -1 | 230,013,133 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 719 | 1,987 | 5,033 | 13,909 | 16,537 | 45,701 | 115,759 | 319,907 | 1,428,653 | 10,000,571 | 32,859,019 | 230,013,133 |
| -1 | -7 | -23 | -161 | -719 | -1,987 | -5,033 | -13,909 | -16,537 | -45,701 | -115,759 | -319,907 | -1,428,653 | -10,000,571 | -32,859,019 | -230,013,133 |
