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 8,411,765, 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 | 8,411,765 | |
| -1 | -8,411,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,411,765.
Example:
1 x 8,411,765 = 8,411,765
and
-1 x -8,411,765 = 8,411,765
Notice both answers equal 8,411,765
With that explanation out of the way, let's continue. Next, we take the number 8,411,765 and divide it by 2:
8,411,765 ÷ 2 = 4,205,882.5
If the quotient is a whole number, then 2 and 4,205,882.5 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 | 8,411,765 | |
| -1 | -8,411,765 |
Now, we try dividing 8,411,765 by 3:
8,411,765 ÷ 3 = 2,803,921.6667
If the quotient is a whole number, then 3 and 2,803,921.6667 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 | 8,411,765 | |
| -1 | -8,411,765 |
Let's try dividing by 4:
8,411,765 ÷ 4 = 2,102,941.25
If the quotient is a whole number, then 4 and 2,102,941.25 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 | 8,411,765 | |
| -1 | 8,411,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 41 | 185 | 205 | 1,109 | 1,517 | 5,545 | 7,585 | 41,033 | 45,469 | 205,165 | 227,345 | 1,682,353 | 8,411,765 |
| -1 | -5 | -37 | -41 | -185 | -205 | -1,109 | -1,517 | -5,545 | -7,585 | -41,033 | -45,469 | -205,165 | -227,345 | -1,682,353 | -8,411,765 |
