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 716,604,317, 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 | 716,604,317 | |
| -1 | -716,604,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 716,604,317.
Example:
1 x 716,604,317 = 716,604,317
and
-1 x -716,604,317 = 716,604,317
Notice both answers equal 716,604,317
With that explanation out of the way, let's continue. Next, we take the number 716,604,317 and divide it by 2:
716,604,317 ÷ 2 = 358,302,158.5
If the quotient is a whole number, then 2 and 358,302,158.5 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 | 716,604,317 | |
| -1 | -716,604,317 |
Now, we try dividing 716,604,317 by 3:
716,604,317 ÷ 3 = 238,868,105.6667
If the quotient is a whole number, then 3 and 238,868,105.6667 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 | 716,604,317 | |
| -1 | -716,604,317 |
Let's try dividing by 4:
716,604,317 ÷ 4 = 179,151,079.25
If the quotient is a whole number, then 4 and 179,151,079.25 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 | 716,604,317 | |
| -1 | 716,604,317 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 587 | 6,457 | 7,631 | 8,537 | 83,941 | 93,907 | 110,981 | 1,220,791 | 5,011,219 | 55,123,409 | 65,145,847 | 716,604,317 |
| -1 | -11 | -13 | -143 | -587 | -6,457 | -7,631 | -8,537 | -83,941 | -93,907 | -110,981 | -1,220,791 | -5,011,219 | -55,123,409 | -65,145,847 | -716,604,317 |
