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 407,495, 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 | 407,495 | |
| -1 | -407,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 407,495.
Example:
1 x 407,495 = 407,495
and
-1 x -407,495 = 407,495
Notice both answers equal 407,495
With that explanation out of the way, let's continue. Next, we take the number 407,495 and divide it by 2:
407,495 ÷ 2 = 203,747.5
If the quotient is a whole number, then 2 and 203,747.5 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 | 407,495 | |
| -1 | -407,495 |
Now, we try dividing 407,495 by 3:
407,495 ÷ 3 = 135,831.6667
If the quotient is a whole number, then 3 and 135,831.6667 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 | 407,495 | |
| -1 | -407,495 |
Let's try dividing by 4:
407,495 ÷ 4 = 101,873.75
If the quotient is a whole number, then 4 and 101,873.75 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 | 407,495 | |
| -1 | 407,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 155 | 239 | 341 | 1,195 | 1,705 | 2,629 | 7,409 | 13,145 | 37,045 | 81,499 | 407,495 |
| -1 | -5 | -11 | -31 | -55 | -155 | -239 | -341 | -1,195 | -1,705 | -2,629 | -7,409 | -13,145 | -37,045 | -81,499 | -407,495 |
