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 8,320,529, 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 | 8,320,529 | |
| -1 | -8,320,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,320,529.
Example:
1 x 8,320,529 = 8,320,529
and
-1 x -8,320,529 = 8,320,529
Notice both answers equal 8,320,529
With that explanation out of the way, let's continue. Next, we take the number 8,320,529 and divide it by 2:
8,320,529 ÷ 2 = 4,160,264.5
If the quotient is a whole number, then 2 and 4,160,264.5 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 | 8,320,529 | |
| -1 | -8,320,529 |
Now, we try dividing 8,320,529 by 3:
8,320,529 ÷ 3 = 2,773,509.6667
If the quotient is a whole number, then 3 and 2,773,509.6667 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 | 8,320,529 | |
| -1 | -8,320,529 |
Let's try dividing by 4:
8,320,529 ÷ 4 = 2,080,132.25
If the quotient is a whole number, then 4 and 2,080,132.25 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 | 8,320,529 | |
| -1 | 8,320,529 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 113 | 157 | 469 | 791 | 1,099 | 7,571 | 10,519 | 17,741 | 52,997 | 73,633 | 124,187 | 1,188,647 | 8,320,529 |
| -1 | -7 | -67 | -113 | -157 | -469 | -791 | -1,099 | -7,571 | -10,519 | -17,741 | -52,997 | -73,633 | -124,187 | -1,188,647 | -8,320,529 |
