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 3,888,535, 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 | 3,888,535 | |
| -1 | -3,888,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,888,535.
Example:
1 x 3,888,535 = 3,888,535
and
-1 x -3,888,535 = 3,888,535
Notice both answers equal 3,888,535
With that explanation out of the way, let's continue. Next, we take the number 3,888,535 and divide it by 2:
3,888,535 ÷ 2 = 1,944,267.5
If the quotient is a whole number, then 2 and 1,944,267.5 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 | 3,888,535 | |
| -1 | -3,888,535 |
Now, we try dividing 3,888,535 by 3:
3,888,535 ÷ 3 = 1,296,178.3333
If the quotient is a whole number, then 3 and 1,296,178.3333 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 | 3,888,535 | |
| -1 | -3,888,535 |
Let's try dividing by 4:
3,888,535 ÷ 4 = 972,133.75
If the quotient is a whole number, then 4 and 972,133.75 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 | 3,888,535 | |
| -1 | 3,888,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 241 | 461 | 1,205 | 1,687 | 2,305 | 3,227 | 8,435 | 16,135 | 111,101 | 555,505 | 777,707 | 3,888,535 |
| -1 | -5 | -7 | -35 | -241 | -461 | -1,205 | -1,687 | -2,305 | -3,227 | -8,435 | -16,135 | -111,101 | -555,505 | -777,707 | -3,888,535 |
