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 320,411,755, 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 | 320,411,755 | |
| -1 | -320,411,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,411,755.
Example:
1 x 320,411,755 = 320,411,755
and
-1 x -320,411,755 = 320,411,755
Notice both answers equal 320,411,755
With that explanation out of the way, let's continue. Next, we take the number 320,411,755 and divide it by 2:
320,411,755 ÷ 2 = 160,205,877.5
If the quotient is a whole number, then 2 and 160,205,877.5 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 | 320,411,755 | |
| -1 | -320,411,755 |
Now, we try dividing 320,411,755 by 3:
320,411,755 ÷ 3 = 106,803,918.3333
If the quotient is a whole number, then 3 and 106,803,918.3333 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 | 320,411,755 | |
| -1 | -320,411,755 |
Let's try dividing by 4:
320,411,755 ÷ 4 = 80,102,938.75
If the quotient is a whole number, then 4 and 80,102,938.75 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 | 320,411,755 | |
| -1 | 320,411,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 79 | 335 | 395 | 5,293 | 12,107 | 26,465 | 60,535 | 811,169 | 956,453 | 4,055,845 | 4,782,265 | 64,082,351 | 320,411,755 |
| -1 | -5 | -67 | -79 | -335 | -395 | -5,293 | -12,107 | -26,465 | -60,535 | -811,169 | -956,453 | -4,055,845 | -4,782,265 | -64,082,351 | -320,411,755 |
