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 4,039,091, 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 | 4,039,091 | |
| -1 | -4,039,091 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 4,039,091.
Example:
1 x 4,039,091 = 4,039,091
and
-1 x -4,039,091 = 4,039,091
Notice both answers equal 4,039,091
With that explanation out of the way, let's continue. Next, we take the number 4,039,091 and divide it by 2:
4,039,091 ÷ 2 = 2,019,545.5
If the quotient is a whole number, then 2 and 2,019,545.5 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 | 4,039,091 | |
| -1 | -4,039,091 |
Now, we try dividing 4,039,091 by 3:
4,039,091 ÷ 3 = 1,346,363.6667
If the quotient is a whole number, then 3 and 1,346,363.6667 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 | 4,039,091 | |
| -1 | -4,039,091 |
Let's try dividing by 4:
4,039,091 ÷ 4 = 1,009,772.75
If the quotient is a whole number, then 4 and 1,009,772.75 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 | 4,039,091 | |
| -1 | 4,039,091 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 101 | 197 | 203 | 707 | 1,379 | 2,929 | 5,713 | 19,897 | 20,503 | 39,991 | 139,279 | 577,013 | 4,039,091 |
| -1 | -7 | -29 | -101 | -197 | -203 | -707 | -1,379 | -2,929 | -5,713 | -19,897 | -20,503 | -39,991 | -139,279 | -577,013 | -4,039,091 |
