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 8,391,295, 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 | 8,391,295 | |
| -1 | -8,391,295 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,391,295.
Example:
1 x 8,391,295 = 8,391,295
and
-1 x -8,391,295 = 8,391,295
Notice both answers equal 8,391,295
With that explanation out of the way, let's continue. Next, we take the number 8,391,295 and divide it by 2:
8,391,295 ÷ 2 = 4,195,647.5
If the quotient is a whole number, then 2 and 4,195,647.5 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 | 8,391,295 | |
| -1 | -8,391,295 |
Now, we try dividing 8,391,295 by 3:
8,391,295 ÷ 3 = 2,797,098.3333
If the quotient is a whole number, then 3 and 2,797,098.3333 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 | 8,391,295 | |
| -1 | -8,391,295 |
Let's try dividing by 4:
8,391,295 ÷ 4 = 2,097,823.75
If the quotient is a whole number, then 4 and 2,097,823.75 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 | 8,391,295 | |
| -1 | 8,391,295 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 5,261 | 26,305 | 57,871 | 152,569 | 289,355 | 762,845 | 1,678,259 | 8,391,295 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -5,261 | -26,305 | -57,871 | -152,569 | -289,355 | -762,845 | -1,678,259 | -8,391,295 |
