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 317,751,301, 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 | 317,751,301 | |
| -1 | -317,751,301 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 317,751,301.
Example:
1 x 317,751,301 = 317,751,301
and
-1 x -317,751,301 = 317,751,301
Notice both answers equal 317,751,301
With that explanation out of the way, let's continue. Next, we take the number 317,751,301 and divide it by 2:
317,751,301 ÷ 2 = 158,875,650.5
If the quotient is a whole number, then 2 and 158,875,650.5 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 | 317,751,301 | |
| -1 | -317,751,301 |
Now, we try dividing 317,751,301 by 3:
317,751,301 ÷ 3 = 105,917,100.3333
If the quotient is a whole number, then 3 and 105,917,100.3333 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 | 317,751,301 | |
| -1 | -317,751,301 |
Let's try dividing by 4:
317,751,301 ÷ 4 = 79,437,825.25
If the quotient is a whole number, then 4 and 79,437,825.25 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 | 317,751,301 | |
| -1 | 317,751,301 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 37 | 119 | 259 | 629 | 4,403 | 72,167 | 505,169 | 1,226,839 | 2,670,179 | 8,587,873 | 18,691,253 | 45,393,043 | 317,751,301 |
| -1 | -7 | -17 | -37 | -119 | -259 | -629 | -4,403 | -72,167 | -505,169 | -1,226,839 | -2,670,179 | -8,587,873 | -18,691,253 | -45,393,043 | -317,751,301 |
