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 8,006,813, 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 | 8,006,813 | |
| -1 | -8,006,813 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,006,813.
Example:
1 x 8,006,813 = 8,006,813
and
-1 x -8,006,813 = 8,006,813
Notice both answers equal 8,006,813
With that explanation out of the way, let's continue. Next, we take the number 8,006,813 and divide it by 2:
8,006,813 ÷ 2 = 4,003,406.5
If the quotient is a whole number, then 2 and 4,003,406.5 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 | 8,006,813 | |
| -1 | -8,006,813 |
Now, we try dividing 8,006,813 by 3:
8,006,813 ÷ 3 = 2,668,937.6667
If the quotient is a whole number, then 3 and 2,668,937.6667 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 | 8,006,813 | |
| -1 | -8,006,813 |
Let's try dividing by 4:
8,006,813 ÷ 4 = 2,001,703.25
If the quotient is a whole number, then 4 and 2,001,703.25 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 | 8,006,813 | |
| -1 | 8,006,813 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 109 | 149 | 493 | 1,853 | 2,533 | 3,161 | 4,321 | 16,241 | 53,737 | 73,457 | 276,097 | 470,989 | 8,006,813 |
| -1 | -17 | -29 | -109 | -149 | -493 | -1,853 | -2,533 | -3,161 | -4,321 | -16,241 | -53,737 | -73,457 | -276,097 | -470,989 | -8,006,813 |
