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 768,563,317, 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 | 768,563,317 | |
| -1 | -768,563,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 768,563,317.
Example:
1 x 768,563,317 = 768,563,317
and
-1 x -768,563,317 = 768,563,317
Notice both answers equal 768,563,317
With that explanation out of the way, let's continue. Next, we take the number 768,563,317 and divide it by 2:
768,563,317 ÷ 2 = 384,281,658.5
If the quotient is a whole number, then 2 and 384,281,658.5 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 | 768,563,317 | |
| -1 | -768,563,317 |
Now, we try dividing 768,563,317 by 3:
768,563,317 ÷ 3 = 256,187,772.3333
If the quotient is a whole number, then 3 and 256,187,772.3333 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 | 768,563,317 | |
| -1 | -768,563,317 |
Let's try dividing by 4:
768,563,317 ÷ 4 = 192,140,829.25
If the quotient is a whole number, then 4 and 192,140,829.25 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 | 768,563,317 | |
| -1 | 768,563,317 |
If you did it right, you will end up with this table:
| 1 | 47 | 83 | 271 | 727 | 3,901 | 12,737 | 22,493 | 34,169 | 60,341 | 197,017 | 1,057,171 | 2,836,027 | 9,259,799 | 16,352,411 | 768,563,317 |
| -1 | -47 | -83 | -271 | -727 | -3,901 | -12,737 | -22,493 | -34,169 | -60,341 | -197,017 | -1,057,171 | -2,836,027 | -9,259,799 | -16,352,411 | -768,563,317 |
