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 3,882,835, 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 | 3,882,835 | |
| -1 | -3,882,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,882,835.
Example:
1 x 3,882,835 = 3,882,835
and
-1 x -3,882,835 = 3,882,835
Notice both answers equal 3,882,835
With that explanation out of the way, let's continue. Next, we take the number 3,882,835 and divide it by 2:
3,882,835 ÷ 2 = 1,941,417.5
If the quotient is a whole number, then 2 and 1,941,417.5 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 | 3,882,835 | |
| -1 | -3,882,835 |
Now, we try dividing 3,882,835 by 3:
3,882,835 ÷ 3 = 1,294,278.3333
If the quotient is a whole number, then 3 and 1,294,278.3333 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 | 3,882,835 | |
| -1 | -3,882,835 |
Let's try dividing by 4:
3,882,835 ÷ 4 = 970,708.75
If the quotient is a whole number, then 4 and 970,708.75 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 | 3,882,835 | |
| -1 | 3,882,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 227 | 311 | 1,135 | 1,555 | 2,497 | 3,421 | 12,485 | 17,105 | 70,597 | 352,985 | 776,567 | 3,882,835 |
| -1 | -5 | -11 | -55 | -227 | -311 | -1,135 | -1,555 | -2,497 | -3,421 | -12,485 | -17,105 | -70,597 | -352,985 | -776,567 | -3,882,835 |
