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 320,443,255, 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 | 320,443,255 | |
| -1 | -320,443,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,443,255.
Example:
1 x 320,443,255 = 320,443,255
and
-1 x -320,443,255 = 320,443,255
Notice both answers equal 320,443,255
With that explanation out of the way, let's continue. Next, we take the number 320,443,255 and divide it by 2:
320,443,255 ÷ 2 = 160,221,627.5
If the quotient is a whole number, then 2 and 160,221,627.5 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 | 320,443,255 | |
| -1 | -320,443,255 |
Now, we try dividing 320,443,255 by 3:
320,443,255 ÷ 3 = 106,814,418.3333
If the quotient is a whole number, then 3 and 106,814,418.3333 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 | 320,443,255 | |
| -1 | -320,443,255 |
Let's try dividing by 4:
320,443,255 ÷ 4 = 80,110,813.75
If the quotient is a whole number, then 4 and 80,110,813.75 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 | 320,443,255 | |
| -1 | 320,443,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 983 | 4,915 | 5,927 | 10,813 | 29,635 | 54,065 | 65,197 | 325,985 | 5,826,241 | 29,131,205 | 64,088,651 | 320,443,255 |
| -1 | -5 | -11 | -55 | -983 | -4,915 | -5,927 | -10,813 | -29,635 | -54,065 | -65,197 | -325,985 | -5,826,241 | -29,131,205 | -64,088,651 | -320,443,255 |
