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 230,320,103, 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 | 230,320,103 | |
| -1 | -230,320,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,320,103.
Example:
1 x 230,320,103 = 230,320,103
and
-1 x -230,320,103 = 230,320,103
Notice both answers equal 230,320,103
With that explanation out of the way, let's continue. Next, we take the number 230,320,103 and divide it by 2:
230,320,103 ÷ 2 = 115,160,051.5
If the quotient is a whole number, then 2 and 115,160,051.5 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 | 230,320,103 | |
| -1 | -230,320,103 |
Now, we try dividing 230,320,103 by 3:
230,320,103 ÷ 3 = 76,773,367.6667
If the quotient is a whole number, then 3 and 76,773,367.6667 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 | 230,320,103 | |
| -1 | -230,320,103 |
Let's try dividing by 4:
230,320,103 ÷ 4 = 57,580,025.75
If the quotient is a whole number, then 4 and 57,580,025.75 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 | 230,320,103 | |
| -1 | 230,320,103 |
If you did it right, you will end up with this table:
| 1 | 13 | 83 | 113 | 1,079 | 1,469 | 1,889 | 9,379 | 24,557 | 121,927 | 156,787 | 213,457 | 2,038,231 | 2,774,941 | 17,716,931 | 230,320,103 |
| -1 | -13 | -83 | -113 | -1,079 | -1,469 | -1,889 | -9,379 | -24,557 | -121,927 | -156,787 | -213,457 | -2,038,231 | -2,774,941 | -17,716,931 | -230,320,103 |
