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 3,908,135, 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 | 3,908,135 | |
| -1 | -3,908,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,908,135.
Example:
1 x 3,908,135 = 3,908,135
and
-1 x -3,908,135 = 3,908,135
Notice both answers equal 3,908,135
With that explanation out of the way, let's continue. Next, we take the number 3,908,135 and divide it by 2:
3,908,135 ÷ 2 = 1,954,067.5
If the quotient is a whole number, then 2 and 1,954,067.5 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 | 3,908,135 | |
| -1 | -3,908,135 |
Now, we try dividing 3,908,135 by 3:
3,908,135 ÷ 3 = 1,302,711.6667
If the quotient is a whole number, then 3 and 1,302,711.6667 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 | 3,908,135 | |
| -1 | -3,908,135 |
Let's try dividing by 4:
3,908,135 ÷ 4 = 977,033.75
If the quotient is a whole number, then 4 and 977,033.75 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 | 3,908,135 | |
| -1 | 3,908,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 10,151 | 50,755 | 71,057 | 111,661 | 355,285 | 558,305 | 781,627 | 3,908,135 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -10,151 | -50,755 | -71,057 | -111,661 | -355,285 | -558,305 | -781,627 | -3,908,135 |
