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 3,930,773, 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 | 3,930,773 | |
| -1 | -3,930,773 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,930,773.
Example:
1 x 3,930,773 = 3,930,773
and
-1 x -3,930,773 = 3,930,773
Notice both answers equal 3,930,773
With that explanation out of the way, let's continue. Next, we take the number 3,930,773 and divide it by 2:
3,930,773 ÷ 2 = 1,965,386.5
If the quotient is a whole number, then 2 and 1,965,386.5 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 | 3,930,773 | |
| -1 | -3,930,773 |
Now, we try dividing 3,930,773 by 3:
3,930,773 ÷ 3 = 1,310,257.6667
If the quotient is a whole number, then 3 and 1,310,257.6667 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 | 3,930,773 | |
| -1 | -3,930,773 |
Let's try dividing by 4:
3,930,773 ÷ 4 = 982,693.25
If the quotient is a whole number, then 4 and 982,693.25 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 | 3,930,773 | |
| -1 | 3,930,773 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 71 | 77 | 497 | 719 | 781 | 5,033 | 5,467 | 7,909 | 51,049 | 55,363 | 357,343 | 561,539 | 3,930,773 |
| -1 | -7 | -11 | -71 | -77 | -497 | -719 | -781 | -5,033 | -5,467 | -7,909 | -51,049 | -55,363 | -357,343 | -561,539 | -3,930,773 |
