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 8,438,755, 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 | 8,438,755 | |
| -1 | -8,438,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,438,755.
Example:
1 x 8,438,755 = 8,438,755
and
-1 x -8,438,755 = 8,438,755
Notice both answers equal 8,438,755
With that explanation out of the way, let's continue. Next, we take the number 8,438,755 and divide it by 2:
8,438,755 ÷ 2 = 4,219,377.5
If the quotient is a whole number, then 2 and 4,219,377.5 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 | 8,438,755 | |
| -1 | -8,438,755 |
Now, we try dividing 8,438,755 by 3:
8,438,755 ÷ 3 = 2,812,918.3333
If the quotient is a whole number, then 3 and 2,812,918.3333 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 | 8,438,755 | |
| -1 | -8,438,755 |
Let's try dividing by 4:
8,438,755 ÷ 4 = 2,109,688.75
If the quotient is a whole number, then 4 and 2,109,688.75 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 | 8,438,755 | |
| -1 | 8,438,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 6,833 | 34,165 | 88,829 | 129,827 | 444,145 | 649,135 | 1,687,751 | 8,438,755 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -6,833 | -34,165 | -88,829 | -129,827 | -444,145 | -649,135 | -1,687,751 | -8,438,755 |
