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 3,944,125, 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 | 3,944,125 | |
| -1 | -3,944,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,944,125.
Example:
1 x 3,944,125 = 3,944,125
and
-1 x -3,944,125 = 3,944,125
Notice both answers equal 3,944,125
With that explanation out of the way, let's continue. Next, we take the number 3,944,125 and divide it by 2:
3,944,125 ÷ 2 = 1,972,062.5
If the quotient is a whole number, then 2 and 1,972,062.5 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 | 3,944,125 | |
| -1 | -3,944,125 |
Now, we try dividing 3,944,125 by 3:
3,944,125 ÷ 3 = 1,314,708.3333
If the quotient is a whole number, then 3 and 1,314,708.3333 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 | 3,944,125 | |
| -1 | -3,944,125 |
Let's try dividing by 4:
3,944,125 ÷ 4 = 986,031.25
If the quotient is a whole number, then 4 and 986,031.25 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 | 3,944,125 | |
| -1 | 3,944,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 139 | 227 | 695 | 1,135 | 3,475 | 5,675 | 17,375 | 28,375 | 31,553 | 157,765 | 788,825 | 3,944,125 |
| -1 | -5 | -25 | -125 | -139 | -227 | -695 | -1,135 | -3,475 | -5,675 | -17,375 | -28,375 | -31,553 | -157,765 | -788,825 | -3,944,125 |
