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 717,377,309, 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 | 717,377,309 | |
| -1 | -717,377,309 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 717,377,309.
Example:
1 x 717,377,309 = 717,377,309
and
-1 x -717,377,309 = 717,377,309
Notice both answers equal 717,377,309
With that explanation out of the way, let's continue. Next, we take the number 717,377,309 and divide it by 2:
717,377,309 ÷ 2 = 358,688,654.5
If the quotient is a whole number, then 2 and 358,688,654.5 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 | 717,377,309 | |
| -1 | -717,377,309 |
Now, we try dividing 717,377,309 by 3:
717,377,309 ÷ 3 = 239,125,769.6667
If the quotient is a whole number, then 3 and 239,125,769.6667 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 | 717,377,309 | |
| -1 | -717,377,309 |
Let's try dividing by 4:
717,377,309 ÷ 4 = 179,344,327.25
If the quotient is a whole number, then 4 and 179,344,327.25 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 | 717,377,309 | |
| -1 | 717,377,309 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 517 | 797 | 1,741 | 8,767 | 19,151 | 37,459 | 81,827 | 412,049 | 900,097 | 1,387,577 | 15,263,347 | 65,216,119 | 717,377,309 |
| -1 | -11 | -47 | -517 | -797 | -1,741 | -8,767 | -19,151 | -37,459 | -81,827 | -412,049 | -900,097 | -1,387,577 | -15,263,347 | -65,216,119 | -717,377,309 |
