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 4,055,909, 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 | 4,055,909 | |
| -1 | -4,055,909 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,055,909.
Example:
1 x 4,055,909 = 4,055,909
and
-1 x -4,055,909 = 4,055,909
Notice both answers equal 4,055,909
With that explanation out of the way, let's continue. Next, we take the number 4,055,909 and divide it by 2:
4,055,909 ÷ 2 = 2,027,954.5
If the quotient is a whole number, then 2 and 2,027,954.5 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 | 4,055,909 | |
| -1 | -4,055,909 |
Now, we try dividing 4,055,909 by 3:
4,055,909 ÷ 3 = 1,351,969.6667
If the quotient is a whole number, then 3 and 1,351,969.6667 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 | 4,055,909 | |
| -1 | -4,055,909 |
Let's try dividing by 4:
4,055,909 ÷ 4 = 1,013,977.25
If the quotient is a whole number, then 4 and 1,013,977.25 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 | 4,055,909 | |
| -1 | 4,055,909 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 113 | 143 | 251 | 1,243 | 1,469 | 2,761 | 3,263 | 16,159 | 28,363 | 35,893 | 311,993 | 368,719 | 4,055,909 |
| -1 | -11 | -13 | -113 | -143 | -251 | -1,243 | -1,469 | -2,761 | -3,263 | -16,159 | -28,363 | -35,893 | -311,993 | -368,719 | -4,055,909 |
