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 82,073,075, 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 | 82,073,075 | |
| -1 | -82,073,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,073,075.
Example:
1 x 82,073,075 = 82,073,075
and
-1 x -82,073,075 = 82,073,075
Notice both answers equal 82,073,075
With that explanation out of the way, let's continue. Next, we take the number 82,073,075 and divide it by 2:
82,073,075 ÷ 2 = 41,036,537.5
If the quotient is a whole number, then 2 and 41,036,537.5 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 | 82,073,075 | |
| -1 | -82,073,075 |
Now, we try dividing 82,073,075 by 3:
82,073,075 ÷ 3 = 27,357,691.6667
If the quotient is a whole number, then 3 and 27,357,691.6667 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 | 82,073,075 | |
| -1 | -82,073,075 |
Let's try dividing by 4:
82,073,075 ÷ 4 = 20,518,268.75
If the quotient is a whole number, then 4 and 20,518,268.75 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 | 82,073,075 | |
| -1 | 82,073,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 175 | 281 | 1,405 | 1,669 | 1,967 | 7,025 | 8,345 | 9,835 | 11,683 | 41,725 | 49,175 | 58,415 | 292,075 | 468,989 | 2,344,945 | 3,282,923 | 11,724,725 | 16,414,615 | 82,073,075 |
| -1 | -5 | -7 | -25 | -35 | -175 | -281 | -1,405 | -1,669 | -1,967 | -7,025 | -8,345 | -9,835 | -11,683 | -41,725 | -49,175 | -58,415 | -292,075 | -468,989 | -2,344,945 | -3,282,923 | -11,724,725 | -16,414,615 | -82,073,075 |
