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 406,945, 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 | 406,945 | |
| -1 | -406,945 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 406,945.
Example:
1 x 406,945 = 406,945
and
-1 x -406,945 = 406,945
Notice both answers equal 406,945
With that explanation out of the way, let's continue. Next, we take the number 406,945 and divide it by 2:
406,945 ÷ 2 = 203,472.5
If the quotient is a whole number, then 2 and 203,472.5 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 | 406,945 | |
| -1 | -406,945 |
Now, we try dividing 406,945 by 3:
406,945 ÷ 3 = 135,648.3333
If the quotient is a whole number, then 3 and 135,648.3333 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 | 406,945 | |
| -1 | -406,945 |
Let's try dividing by 4:
406,945 ÷ 4 = 101,736.25
If the quotient is a whole number, then 4 and 101,736.25 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 | 406,945 | |
| -1 | 406,945 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 151 | 245 | 385 | 539 | 755 | 1,057 | 1,661 | 2,695 | 5,285 | 7,399 | 8,305 | 11,627 | 36,995 | 58,135 | 81,389 | 406,945 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -151 | -245 | -385 | -539 | -755 | -1,057 | -1,661 | -2,695 | -5,285 | -7,399 | -8,305 | -11,627 | -36,995 | -58,135 | -81,389 | -406,945 |
