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 404,915, 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 | 404,915 | |
| -1 | -404,915 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 404,915.
Example:
1 x 404,915 = 404,915
and
-1 x -404,915 = 404,915
Notice both answers equal 404,915
With that explanation out of the way, let's continue. Next, we take the number 404,915 and divide it by 2:
404,915 ÷ 2 = 202,457.5
If the quotient is a whole number, then 2 and 202,457.5 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 | 404,915 | |
| -1 | -404,915 |
Now, we try dividing 404,915 by 3:
404,915 ÷ 3 = 134,971.6667
If the quotient is a whole number, then 3 and 134,971.6667 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 | 404,915 | |
| -1 | -404,915 |
Let's try dividing by 4:
404,915 ÷ 4 = 101,228.75
If the quotient is a whole number, then 4 and 101,228.75 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 | 404,915 | |
| -1 | 404,915 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 503 | 805 | 2,515 | 3,521 | 11,569 | 17,605 | 57,845 | 80,983 | 404,915 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -503 | -805 | -2,515 | -3,521 | -11,569 | -17,605 | -57,845 | -80,983 | -404,915 |
