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 317,623,355, 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 | 317,623,355 | |
| -1 | -317,623,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 317,623,355.
Example:
1 x 317,623,355 = 317,623,355
and
-1 x -317,623,355 = 317,623,355
Notice both answers equal 317,623,355
With that explanation out of the way, let's continue. Next, we take the number 317,623,355 and divide it by 2:
317,623,355 ÷ 2 = 158,811,677.5
If the quotient is a whole number, then 2 and 158,811,677.5 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 | 317,623,355 | |
| -1 | -317,623,355 |
Now, we try dividing 317,623,355 by 3:
317,623,355 ÷ 3 = 105,874,451.6667
If the quotient is a whole number, then 3 and 105,874,451.6667 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 | 317,623,355 | |
| -1 | -317,623,355 |
Let's try dividing by 4:
317,623,355 ÷ 4 = 79,405,838.75
If the quotient is a whole number, then 4 and 79,405,838.75 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 | 317,623,355 | |
| -1 | 317,623,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 185 | 259 | 1,295 | 245,269 | 1,226,345 | 1,716,883 | 8,584,415 | 9,074,953 | 45,374,765 | 63,524,671 | 317,623,355 |
| -1 | -5 | -7 | -35 | -37 | -185 | -259 | -1,295 | -245,269 | -1,226,345 | -1,716,883 | -8,584,415 | -9,074,953 | -45,374,765 | -63,524,671 | -317,623,355 |
