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 230,013,455, 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 | 230,013,455 | |
| -1 | -230,013,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,013,455.
Example:
1 x 230,013,455 = 230,013,455
and
-1 x -230,013,455 = 230,013,455
Notice both answers equal 230,013,455
With that explanation out of the way, let's continue. Next, we take the number 230,013,455 and divide it by 2:
230,013,455 ÷ 2 = 115,006,727.5
If the quotient is a whole number, then 2 and 115,006,727.5 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 | 230,013,455 | |
| -1 | -230,013,455 |
Now, we try dividing 230,013,455 by 3:
230,013,455 ÷ 3 = 76,671,151.6667
If the quotient is a whole number, then 3 and 76,671,151.6667 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 | 230,013,455 | |
| -1 | -230,013,455 |
Let's try dividing by 4:
230,013,455 ÷ 4 = 57,503,363.75
If the quotient is a whole number, then 4 and 57,503,363.75 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 | 230,013,455 | |
| -1 | 230,013,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 285,731 | 1,428,655 | 2,000,117 | 6,571,813 | 10,000,585 | 32,859,065 | 46,002,691 | 230,013,455 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -285,731 | -1,428,655 | -2,000,117 | -6,571,813 | -10,000,585 | -32,859,065 | -46,002,691 | -230,013,455 |
