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 3,040,919, 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 | 3,040,919 | |
| -1 | -3,040,919 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,040,919.
Example:
1 x 3,040,919 = 3,040,919
and
-1 x -3,040,919 = 3,040,919
Notice both answers equal 3,040,919
With that explanation out of the way, let's continue. Next, we take the number 3,040,919 and divide it by 2:
3,040,919 ÷ 2 = 1,520,459.5
If the quotient is a whole number, then 2 and 1,520,459.5 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 | 3,040,919 | |
| -1 | -3,040,919 |
Now, we try dividing 3,040,919 by 3:
3,040,919 ÷ 3 = 1,013,639.6667
If the quotient is a whole number, then 3 and 1,013,639.6667 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 | 3,040,919 | |
| -1 | -3,040,919 |
Let's try dividing by 4:
3,040,919 ÷ 4 = 760,229.75
If the quotient is a whole number, then 4 and 760,229.75 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 | 3,040,919 | |
| -1 | 3,040,919 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 59 | 199 | 259 | 413 | 1,393 | 2,183 | 7,363 | 11,741 | 15,281 | 51,541 | 82,187 | 434,417 | 3,040,919 |
| -1 | -7 | -37 | -59 | -199 | -259 | -413 | -1,393 | -2,183 | -7,363 | -11,741 | -15,281 | -51,541 | -82,187 | -434,417 | -3,040,919 |
