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 317,307,625, 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 | 317,307,625 | |
| -1 | -317,307,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 317,307,625.
Example:
1 x 317,307,625 = 317,307,625
and
-1 x -317,307,625 = 317,307,625
Notice both answers equal 317,307,625
With that explanation out of the way, let's continue. Next, we take the number 317,307,625 and divide it by 2:
317,307,625 ÷ 2 = 158,653,812.5
If the quotient is a whole number, then 2 and 158,653,812.5 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 | 317,307,625 | |
| -1 | -317,307,625 |
Now, we try dividing 317,307,625 by 3:
317,307,625 ÷ 3 = 105,769,208.3333
If the quotient is a whole number, then 3 and 105,769,208.3333 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 | 317,307,625 | |
| -1 | -317,307,625 |
Let's try dividing by 4:
317,307,625 ÷ 4 = 79,326,906.25
If the quotient is a whole number, then 4 and 79,326,906.25 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 | 317,307,625 | |
| -1 | 317,307,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 151 | 755 | 3,775 | 16,811 | 18,875 | 84,055 | 420,275 | 2,101,375 | 2,538,461 | 12,692,305 | 63,461,525 | 317,307,625 |
| -1 | -5 | -25 | -125 | -151 | -755 | -3,775 | -16,811 | -18,875 | -84,055 | -420,275 | -2,101,375 | -2,538,461 | -12,692,305 | -63,461,525 | -317,307,625 |
