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 357,102,317, 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 | 357,102,317 | |
| -1 | -357,102,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 357,102,317.
Example:
1 x 357,102,317 = 357,102,317
and
-1 x -357,102,317 = 357,102,317
Notice both answers equal 357,102,317
With that explanation out of the way, let's continue. Next, we take the number 357,102,317 and divide it by 2:
357,102,317 ÷ 2 = 178,551,158.5
If the quotient is a whole number, then 2 and 178,551,158.5 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 | 357,102,317 | |
| -1 | -357,102,317 |
Now, we try dividing 357,102,317 by 3:
357,102,317 ÷ 3 = 119,034,105.6667
If the quotient is a whole number, then 3 and 119,034,105.6667 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 | 357,102,317 | |
| -1 | -357,102,317 |
Let's try dividing by 4:
357,102,317 ÷ 4 = 89,275,579.25
If the quotient is a whole number, then 4 and 89,275,579.25 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 | 357,102,317 | |
| -1 | 357,102,317 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 29 | 143 | 319 | 377 | 4,147 | 86,111 | 947,221 | 1,119,443 | 2,497,219 | 12,313,873 | 27,469,409 | 32,463,847 | 357,102,317 |
| -1 | -11 | -13 | -29 | -143 | -319 | -377 | -4,147 | -86,111 | -947,221 | -1,119,443 | -2,497,219 | -12,313,873 | -27,469,409 | -32,463,847 | -357,102,317 |
