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 403,325, 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 | 403,325 | |
| -1 | -403,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,325.
Example:
1 x 403,325 = 403,325
and
-1 x -403,325 = 403,325
Notice both answers equal 403,325
With that explanation out of the way, let's continue. Next, we take the number 403,325 and divide it by 2:
403,325 ÷ 2 = 201,662.5
If the quotient is a whole number, then 2 and 201,662.5 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 | 403,325 | |
| -1 | -403,325 |
Now, we try dividing 403,325 by 3:
403,325 ÷ 3 = 134,441.6667
If the quotient is a whole number, then 3 and 134,441.6667 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 | 403,325 | |
| -1 | -403,325 |
Let's try dividing by 4:
403,325 ÷ 4 = 100,831.25
If the quotient is a whole number, then 4 and 100,831.25 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 | 403,325 | |
| -1 | 403,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 25 | 65 | 73 | 85 | 221 | 325 | 365 | 425 | 949 | 1,105 | 1,241 | 1,825 | 4,745 | 5,525 | 6,205 | 16,133 | 23,725 | 31,025 | 80,665 | 403,325 |
| -1 | -5 | -13 | -17 | -25 | -65 | -73 | -85 | -221 | -325 | -365 | -425 | -949 | -1,105 | -1,241 | -1,825 | -4,745 | -5,525 | -6,205 | -16,133 | -23,725 | -31,025 | -80,665 | -403,325 |
