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 230,013,329, 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 | 230,013,329 | |
| -1 | -230,013,329 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,013,329.
Example:
1 x 230,013,329 = 230,013,329
and
-1 x -230,013,329 = 230,013,329
Notice both answers equal 230,013,329
With that explanation out of the way, let's continue. Next, we take the number 230,013,329 and divide it by 2:
230,013,329 ÷ 2 = 115,006,664.5
If the quotient is a whole number, then 2 and 115,006,664.5 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 | 230,013,329 | |
| -1 | -230,013,329 |
Now, we try dividing 230,013,329 by 3:
230,013,329 ÷ 3 = 76,671,109.6667
If the quotient is a whole number, then 3 and 76,671,109.6667 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 | 230,013,329 | |
| -1 | -230,013,329 |
Let's try dividing by 4:
230,013,329 ÷ 4 = 57,503,332.25
If the quotient is a whole number, then 4 and 57,503,332.25 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 | 230,013,329 | |
| -1 | 230,013,329 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 59 | 91 | 413 | 767 | 5,369 | 42,841 | 299,887 | 556,933 | 2,527,619 | 3,898,531 | 17,693,333 | 32,859,047 | 230,013,329 |
| -1 | -7 | -13 | -59 | -91 | -413 | -767 | -5,369 | -42,841 | -299,887 | -556,933 | -2,527,619 | -3,898,531 | -17,693,333 | -32,859,047 | -230,013,329 |
