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 7,982,375, 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 | 7,982,375 | |
| -1 | -7,982,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,982,375.
Example:
1 x 7,982,375 = 7,982,375
and
-1 x -7,982,375 = 7,982,375
Notice both answers equal 7,982,375
With that explanation out of the way, let's continue. Next, we take the number 7,982,375 and divide it by 2:
7,982,375 ÷ 2 = 3,991,187.5
If the quotient is a whole number, then 2 and 3,991,187.5 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 | 7,982,375 | |
| -1 | -7,982,375 |
Now, we try dividing 7,982,375 by 3:
7,982,375 ÷ 3 = 2,660,791.6667
If the quotient is a whole number, then 3 and 2,660,791.6667 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 | 7,982,375 | |
| -1 | -7,982,375 |
Let's try dividing by 4:
7,982,375 ÷ 4 = 1,995,593.75
If the quotient is a whole number, then 4 and 1,995,593.75 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 | 7,982,375 | |
| -1 | 7,982,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 125 | 475 | 2,375 | 3,361 | 16,805 | 63,859 | 84,025 | 319,295 | 420,125 | 1,596,475 | 7,982,375 |
| -1 | -5 | -19 | -25 | -95 | -125 | -475 | -2,375 | -3,361 | -16,805 | -63,859 | -84,025 | -319,295 | -420,125 | -1,596,475 | -7,982,375 |
