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 317,307,725, 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 | 317,307,725 | |
| -1 | -317,307,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 317,307,725.
Example:
1 x 317,307,725 = 317,307,725
and
-1 x -317,307,725 = 317,307,725
Notice both answers equal 317,307,725
With that explanation out of the way, let's continue. Next, we take the number 317,307,725 and divide it by 2:
317,307,725 ÷ 2 = 158,653,862.5
If the quotient is a whole number, then 2 and 158,653,862.5 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 | 317,307,725 | |
| -1 | -317,307,725 |
Now, we try dividing 317,307,725 by 3:
317,307,725 ÷ 3 = 105,769,241.6667
If the quotient is a whole number, then 3 and 105,769,241.6667 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 | 317,307,725 | |
| -1 | -317,307,725 |
Let's try dividing by 4:
317,307,725 ÷ 4 = 79,326,931.25
If the quotient is a whole number, then 4 and 79,326,931.25 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 | 317,307,725 | |
| -1 | 317,307,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 919 | 1,973 | 4,595 | 6,433 | 9,865 | 13,811 | 22,975 | 32,165 | 49,325 | 69,055 | 160,825 | 345,275 | 1,813,187 | 9,065,935 | 12,692,309 | 45,329,675 | 63,461,545 | 317,307,725 |
| -1 | -5 | -7 | -25 | -35 | -175 | -919 | -1,973 | -4,595 | -6,433 | -9,865 | -13,811 | -22,975 | -32,165 | -49,325 | -69,055 | -160,825 | -345,275 | -1,813,187 | -9,065,935 | -12,692,309 | -45,329,675 | -63,461,545 | -317,307,725 |
