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 517,441,715, 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 | 517,441,715 | |
| -1 | -517,441,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 517,441,715.
Example:
1 x 517,441,715 = 517,441,715
and
-1 x -517,441,715 = 517,441,715
Notice both answers equal 517,441,715
With that explanation out of the way, let's continue. Next, we take the number 517,441,715 and divide it by 2:
517,441,715 ÷ 2 = 258,720,857.5
If the quotient is a whole number, then 2 and 258,720,857.5 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 | 517,441,715 | |
| -1 | -517,441,715 |
Now, we try dividing 517,441,715 by 3:
517,441,715 ÷ 3 = 172,480,571.6667
If the quotient is a whole number, then 3 and 172,480,571.6667 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 | 517,441,715 | |
| -1 | -517,441,715 |
Let's try dividing by 4:
517,441,715 ÷ 4 = 129,360,428.75
If the quotient is a whole number, then 4 and 129,360,428.75 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 | 517,441,715 | |
| -1 | 517,441,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 2,112,007 | 10,560,035 | 14,784,049 | 73,920,245 | 103,488,343 | 517,441,715 |
| -1 | -5 | -7 | -35 | -49 | -245 | -2,112,007 | -10,560,035 | -14,784,049 | -73,920,245 | -103,488,343 | -517,441,715 |
