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 82,958,939, 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 | 82,958,939 | |
| -1 | -82,958,939 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,958,939.
Example:
1 x 82,958,939 = 82,958,939
and
-1 x -82,958,939 = 82,958,939
Notice both answers equal 82,958,939
With that explanation out of the way, let's continue. Next, we take the number 82,958,939 and divide it by 2:
82,958,939 ÷ 2 = 41,479,469.5
If the quotient is a whole number, then 2 and 41,479,469.5 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 | 82,958,939 | |
| -1 | -82,958,939 |
Now, we try dividing 82,958,939 by 3:
82,958,939 ÷ 3 = 27,652,979.6667
If the quotient is a whole number, then 3 and 27,652,979.6667 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 | 82,958,939 | |
| -1 | -82,958,939 |
Let's try dividing by 4:
82,958,939 ÷ 4 = 20,739,734.75
If the quotient is a whole number, then 4 and 20,739,734.75 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 | 82,958,939 | |
| -1 | 82,958,939 |
If you did it right, you will end up with this table:
| 1 | 7 | 53 | 311 | 371 | 719 | 2,177 | 5,033 | 16,483 | 38,107 | 115,381 | 223,609 | 266,749 | 1,565,263 | 11,851,277 | 82,958,939 |
| -1 | -7 | -53 | -311 | -371 | -719 | -2,177 | -5,033 | -16,483 | -38,107 | -115,381 | -223,609 | -266,749 | -1,565,263 | -11,851,277 | -82,958,939 |
