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 8,008,247, 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 | 8,008,247 | |
| -1 | -8,008,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,008,247.
Example:
1 x 8,008,247 = 8,008,247
and
-1 x -8,008,247 = 8,008,247
Notice both answers equal 8,008,247
With that explanation out of the way, let's continue. Next, we take the number 8,008,247 and divide it by 2:
8,008,247 ÷ 2 = 4,004,123.5
If the quotient is a whole number, then 2 and 4,004,123.5 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 | 8,008,247 | |
| -1 | -8,008,247 |
Now, we try dividing 8,008,247 by 3:
8,008,247 ÷ 3 = 2,669,415.6667
If the quotient is a whole number, then 3 and 2,669,415.6667 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 | 8,008,247 | |
| -1 | -8,008,247 |
Let's try dividing by 4:
8,008,247 ÷ 4 = 2,002,061.75
If the quotient is a whole number, then 4 and 2,002,061.75 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 | 8,008,247 | |
| -1 | 8,008,247 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 59 | 197 | 689 | 767 | 2,561 | 3,127 | 10,441 | 11,623 | 40,651 | 135,733 | 151,099 | 616,019 | 8,008,247 |
| -1 | -13 | -53 | -59 | -197 | -689 | -767 | -2,561 | -3,127 | -10,441 | -11,623 | -40,651 | -135,733 | -151,099 | -616,019 | -8,008,247 |
