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 320,332,103, 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 | 320,332,103 | |
| -1 | -320,332,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,332,103.
Example:
1 x 320,332,103 = 320,332,103
and
-1 x -320,332,103 = 320,332,103
Notice both answers equal 320,332,103
With that explanation out of the way, let's continue. Next, we take the number 320,332,103 and divide it by 2:
320,332,103 ÷ 2 = 160,166,051.5
If the quotient is a whole number, then 2 and 160,166,051.5 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 | 320,332,103 | |
| -1 | -320,332,103 |
Now, we try dividing 320,332,103 by 3:
320,332,103 ÷ 3 = 106,777,367.6667
If the quotient is a whole number, then 3 and 106,777,367.6667 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 | 320,332,103 | |
| -1 | -320,332,103 |
Let's try dividing by 4:
320,332,103 ÷ 4 = 80,083,025.75
If the quotient is a whole number, then 4 and 80,083,025.75 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 | 320,332,103 | |
| -1 | 320,332,103 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 73 | 91 | 511 | 949 | 6,643 | 48,221 | 337,547 | 626,873 | 3,520,133 | 4,388,111 | 24,640,931 | 45,761,729 | 320,332,103 |
| -1 | -7 | -13 | -73 | -91 | -511 | -949 | -6,643 | -48,221 | -337,547 | -626,873 | -3,520,133 | -4,388,111 | -24,640,931 | -45,761,729 | -320,332,103 |
