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 317,301,775, 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 | 317,301,775 | |
| -1 | -317,301,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 317,301,775.
Example:
1 x 317,301,775 = 317,301,775
and
-1 x -317,301,775 = 317,301,775
Notice both answers equal 317,301,775
With that explanation out of the way, let's continue. Next, we take the number 317,301,775 and divide it by 2:
317,301,775 ÷ 2 = 158,650,887.5
If the quotient is a whole number, then 2 and 158,650,887.5 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 | 317,301,775 | |
| -1 | -317,301,775 |
Now, we try dividing 317,301,775 by 3:
317,301,775 ÷ 3 = 105,767,258.3333
If the quotient is a whole number, then 3 and 105,767,258.3333 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 | 317,301,775 | |
| -1 | -317,301,775 |
Let's try dividing by 4:
317,301,775 ÷ 4 = 79,325,443.75
If the quotient is a whole number, then 4 and 79,325,443.75 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 | 317,301,775 | |
| -1 | 317,301,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 373 | 1,865 | 2,611 | 4,861 | 9,325 | 13,055 | 24,305 | 34,027 | 65,275 | 121,525 | 170,135 | 850,675 | 1,813,153 | 9,065,765 | 12,692,071 | 45,328,825 | 63,460,355 | 317,301,775 |
| -1 | -5 | -7 | -25 | -35 | -175 | -373 | -1,865 | -2,611 | -4,861 | -9,325 | -13,055 | -24,305 | -34,027 | -65,275 | -121,525 | -170,135 | -850,675 | -1,813,153 | -9,065,765 | -12,692,071 | -45,328,825 | -63,460,355 | -317,301,775 |
