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 230,213,005, 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 | 230,213,005 | |
| -1 | -230,213,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,213,005.
Example:
1 x 230,213,005 = 230,213,005
and
-1 x -230,213,005 = 230,213,005
Notice both answers equal 230,213,005
With that explanation out of the way, let's continue. Next, we take the number 230,213,005 and divide it by 2:
230,213,005 ÷ 2 = 115,106,502.5
If the quotient is a whole number, then 2 and 115,106,502.5 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 | 230,213,005 | |
| -1 | -230,213,005 |
Now, we try dividing 230,213,005 by 3:
230,213,005 ÷ 3 = 76,737,668.3333
If the quotient is a whole number, then 3 and 76,737,668.3333 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 | 230,213,005 | |
| -1 | -230,213,005 |
Let's try dividing by 4:
230,213,005 ÷ 4 = 57,553,251.25
If the quotient is a whole number, then 4 and 57,553,251.25 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 | 230,213,005 | |
| -1 | 230,213,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 67 | 335 | 737 | 3,685 | 62,473 | 312,365 | 687,203 | 3,436,015 | 4,185,691 | 20,928,455 | 46,042,601 | 230,213,005 |
| -1 | -5 | -11 | -55 | -67 | -335 | -737 | -3,685 | -62,473 | -312,365 | -687,203 | -3,436,015 | -4,185,691 | -20,928,455 | -46,042,601 | -230,213,005 |
