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 82,906,681, 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 | 82,906,681 | |
| -1 | -82,906,681 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,906,681.
Example:
1 x 82,906,681 = 82,906,681
and
-1 x -82,906,681 = 82,906,681
Notice both answers equal 82,906,681
With that explanation out of the way, let's continue. Next, we take the number 82,906,681 and divide it by 2:
82,906,681 ÷ 2 = 41,453,340.5
If the quotient is a whole number, then 2 and 41,453,340.5 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 | 82,906,681 | |
| -1 | -82,906,681 |
Now, we try dividing 82,906,681 by 3:
82,906,681 ÷ 3 = 27,635,560.3333
If the quotient is a whole number, then 3 and 27,635,560.3333 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 | 82,906,681 | |
| -1 | -82,906,681 |
Let's try dividing by 4:
82,906,681 ÷ 4 = 20,726,670.25
If the quotient is a whole number, then 4 and 20,726,670.25 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 | 82,906,681 | |
| -1 | 82,906,681 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 53 | 143 | 583 | 689 | 7,579 | 10,939 | 120,329 | 142,207 | 579,767 | 1,564,277 | 6,377,437 | 7,536,971 | 82,906,681 |
| -1 | -11 | -13 | -53 | -143 | -583 | -689 | -7,579 | -10,939 | -120,329 | -142,207 | -579,767 | -1,564,277 | -6,377,437 | -7,536,971 | -82,906,681 |
