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 82,832,761, 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 | 82,832,761 | |
| -1 | -82,832,761 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,832,761.
Example:
1 x 82,832,761 = 82,832,761
and
-1 x -82,832,761 = 82,832,761
Notice both answers equal 82,832,761
With that explanation out of the way, let's continue. Next, we take the number 82,832,761 and divide it by 2:
82,832,761 ÷ 2 = 41,416,380.5
If the quotient is a whole number, then 2 and 41,416,380.5 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 | 82,832,761 | |
| -1 | -82,832,761 |
Now, we try dividing 82,832,761 by 3:
82,832,761 ÷ 3 = 27,610,920.3333
If the quotient is a whole number, then 3 and 27,610,920.3333 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 | 82,832,761 | |
| -1 | -82,832,761 |
Let's try dividing by 4:
82,832,761 ÷ 4 = 20,708,190.25
If the quotient is a whole number, then 4 and 20,708,190.25 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 | 82,832,761 | |
| -1 | 82,832,761 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 209 | 251 | 1,579 | 2,761 | 4,769 | 17,369 | 30,001 | 52,459 | 330,011 | 396,329 | 4,359,619 | 7,530,251 | 82,832,761 |
| -1 | -11 | -19 | -209 | -251 | -1,579 | -2,761 | -4,769 | -17,369 | -30,001 | -52,459 | -330,011 | -396,329 | -4,359,619 | -7,530,251 | -82,832,761 |
