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 8,766,905, 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 | 8,766,905 | |
| -1 | -8,766,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,766,905.
Example:
1 x 8,766,905 = 8,766,905
and
-1 x -8,766,905 = 8,766,905
Notice both answers equal 8,766,905
With that explanation out of the way, let's continue. Next, we take the number 8,766,905 and divide it by 2:
8,766,905 ÷ 2 = 4,383,452.5
If the quotient is a whole number, then 2 and 4,383,452.5 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 | 8,766,905 | |
| -1 | -8,766,905 |
Now, we try dividing 8,766,905 by 3:
8,766,905 ÷ 3 = 2,922,301.6667
If the quotient is a whole number, then 3 and 2,922,301.6667 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 | 8,766,905 | |
| -1 | -8,766,905 |
Let's try dividing by 4:
8,766,905 ÷ 4 = 2,191,726.25
If the quotient is a whole number, then 4 and 2,191,726.25 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 | 8,766,905 | |
| -1 | 8,766,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 463 | 541 | 2,315 | 2,705 | 3,241 | 3,787 | 16,205 | 18,935 | 250,483 | 1,252,415 | 1,753,381 | 8,766,905 |
| -1 | -5 | -7 | -35 | -463 | -541 | -2,315 | -2,705 | -3,241 | -3,787 | -16,205 | -18,935 | -250,483 | -1,252,415 | -1,753,381 | -8,766,905 |
