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 8,810,641, 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 | 8,810,641 | |
| -1 | -8,810,641 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,810,641.
Example:
1 x 8,810,641 = 8,810,641
and
-1 x -8,810,641 = 8,810,641
Notice both answers equal 8,810,641
With that explanation out of the way, let's continue. Next, we take the number 8,810,641 and divide it by 2:
8,810,641 ÷ 2 = 4,405,320.5
If the quotient is a whole number, then 2 and 4,405,320.5 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 | 8,810,641 | |
| -1 | -8,810,641 |
Now, we try dividing 8,810,641 by 3:
8,810,641 ÷ 3 = 2,936,880.3333
If the quotient is a whole number, then 3 and 2,936,880.3333 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 | 8,810,641 | |
| -1 | -8,810,641 |
Let's try dividing by 4:
8,810,641 ÷ 4 = 2,202,660.25
If the quotient is a whole number, then 4 and 2,202,660.25 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 | 8,810,641 | |
| -1 | 8,810,641 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 49 | 119 | 343 | 833 | 1,511 | 5,831 | 10,577 | 25,687 | 74,039 | 179,809 | 518,273 | 1,258,663 | 8,810,641 |
| -1 | -7 | -17 | -49 | -119 | -343 | -833 | -1,511 | -5,831 | -10,577 | -25,687 | -74,039 | -179,809 | -518,273 | -1,258,663 | -8,810,641 |
