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 230,000,015, 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 | 230,000,015 | |
| -1 | -230,000,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,000,015.
Example:
1 x 230,000,015 = 230,000,015
and
-1 x -230,000,015 = 230,000,015
Notice both answers equal 230,000,015
With that explanation out of the way, let's continue. Next, we take the number 230,000,015 and divide it by 2:
230,000,015 ÷ 2 = 115,000,007.5
If the quotient is a whole number, then 2 and 115,000,007.5 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 | 230,000,015 | |
| -1 | -230,000,015 |
Now, we try dividing 230,000,015 by 3:
230,000,015 ÷ 3 = 76,666,671.6667
If the quotient is a whole number, then 3 and 76,666,671.6667 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 | 230,000,015 | |
| -1 | -230,000,015 |
Let's try dividing by 4:
230,000,015 ÷ 4 = 57,500,003.75
If the quotient is a whole number, then 4 and 57,500,003.75 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 | 230,000,015 | |
| -1 | 230,000,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 226,601 | 1,133,005 | 1,586,207 | 6,571,429 | 7,931,035 | 32,857,145 | 46,000,003 | 230,000,015 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -226,601 | -1,133,005 | -1,586,207 | -6,571,429 | -7,931,035 | -32,857,145 | -46,000,003 | -230,000,015 |
