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 8,813,815, 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 | 8,813,815 | |
| -1 | -8,813,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,813,815.
Example:
1 x 8,813,815 = 8,813,815
and
-1 x -8,813,815 = 8,813,815
Notice both answers equal 8,813,815
With that explanation out of the way, let's continue. Next, we take the number 8,813,815 and divide it by 2:
8,813,815 ÷ 2 = 4,406,907.5
If the quotient is a whole number, then 2 and 4,406,907.5 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 | 8,813,815 | |
| -1 | -8,813,815 |
Now, we try dividing 8,813,815 by 3:
8,813,815 ÷ 3 = 2,937,938.3333
If the quotient is a whole number, then 3 and 2,937,938.3333 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 | 8,813,815 | |
| -1 | -8,813,815 |
Let's try dividing by 4:
8,813,815 ÷ 4 = 2,203,453.75
If the quotient is a whole number, then 4 and 2,203,453.75 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 | 8,813,815 | |
| -1 | 8,813,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 257 | 361 | 1,285 | 1,805 | 4,883 | 6,859 | 24,415 | 34,295 | 92,777 | 463,885 | 1,762,763 | 8,813,815 |
| -1 | -5 | -19 | -95 | -257 | -361 | -1,285 | -1,805 | -4,883 | -6,859 | -24,415 | -34,295 | -92,777 | -463,885 | -1,762,763 | -8,813,815 |
