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 317,975, 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 | 317,975 | |
| -1 | -317,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 317,975.
Example:
1 x 317,975 = 317,975
and
-1 x -317,975 = 317,975
Notice both answers equal 317,975
With that explanation out of the way, let's continue. Next, we take the number 317,975 and divide it by 2:
317,975 ÷ 2 = 158,987.5
If the quotient is a whole number, then 2 and 158,987.5 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 | 317,975 | |
| -1 | -317,975 |
Now, we try dividing 317,975 by 3:
317,975 ÷ 3 = 105,991.6667
If the quotient is a whole number, then 3 and 105,991.6667 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 | 317,975 | |
| -1 | -317,975 |
Let's try dividing by 4:
317,975 ÷ 4 = 79,493.75
If the quotient is a whole number, then 4 and 79,493.75 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 | 317,975 | |
| -1 | 317,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 25 | 35 | 79 | 115 | 161 | 175 | 395 | 553 | 575 | 805 | 1,817 | 1,975 | 2,765 | 4,025 | 9,085 | 12,719 | 13,825 | 45,425 | 63,595 | 317,975 |
| -1 | -5 | -7 | -23 | -25 | -35 | -79 | -115 | -161 | -175 | -395 | -553 | -575 | -805 | -1,817 | -1,975 | -2,765 | -4,025 | -9,085 | -12,719 | -13,825 | -45,425 | -63,595 | -317,975 |
