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 323,103,443, 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 | 323,103,443 | |
| -1 | -323,103,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 323,103,443.
Example:
1 x 323,103,443 = 323,103,443
and
-1 x -323,103,443 = 323,103,443
Notice both answers equal 323,103,443
With that explanation out of the way, let's continue. Next, we take the number 323,103,443 and divide it by 2:
323,103,443 ÷ 2 = 161,551,721.5
If the quotient is a whole number, then 2 and 161,551,721.5 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 | 323,103,443 | |
| -1 | -323,103,443 |
Now, we try dividing 323,103,443 by 3:
323,103,443 ÷ 3 = 107,701,147.6667
If the quotient is a whole number, then 3 and 107,701,147.6667 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 | 323,103,443 | |
| -1 | -323,103,443 |
Let's try dividing by 4:
323,103,443 ÷ 4 = 80,775,860.75
If the quotient is a whole number, then 4 and 80,775,860.75 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 | 323,103,443 | |
| -1 | 323,103,443 |
If you did it right, you will end up with this table:
| 1 | 13 | 79 | 197 | 1,027 | 1,597 | 2,561 | 15,563 | 20,761 | 126,163 | 202,319 | 314,609 | 1,640,119 | 4,089,917 | 24,854,111 | 323,103,443 |
| -1 | -13 | -79 | -197 | -1,027 | -1,597 | -2,561 | -15,563 | -20,761 | -126,163 | -202,319 | -314,609 | -1,640,119 | -4,089,917 | -24,854,111 | -323,103,443 |
