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 3,842,905, 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 | 3,842,905 | |
| -1 | -3,842,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,842,905.
Example:
1 x 3,842,905 = 3,842,905
and
-1 x -3,842,905 = 3,842,905
Notice both answers equal 3,842,905
With that explanation out of the way, let's continue. Next, we take the number 3,842,905 and divide it by 2:
3,842,905 ÷ 2 = 1,921,452.5
If the quotient is a whole number, then 2 and 1,921,452.5 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 | 3,842,905 | |
| -1 | -3,842,905 |
Now, we try dividing 3,842,905 by 3:
3,842,905 ÷ 3 = 1,280,968.3333
If the quotient is a whole number, then 3 and 1,280,968.3333 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 | 3,842,905 | |
| -1 | -3,842,905 |
Let's try dividing by 4:
3,842,905 ÷ 4 = 960,726.25
If the quotient is a whole number, then 4 and 960,726.25 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 | 3,842,905 | |
| -1 | 3,842,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 107 | 535 | 653 | 1,177 | 3,265 | 5,885 | 7,183 | 35,915 | 69,871 | 349,355 | 768,581 | 3,842,905 |
| -1 | -5 | -11 | -55 | -107 | -535 | -653 | -1,177 | -3,265 | -5,885 | -7,183 | -35,915 | -69,871 | -349,355 | -768,581 | -3,842,905 |
