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 8,106,965, 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 | 8,106,965 | |
| -1 | -8,106,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,106,965.
Example:
1 x 8,106,965 = 8,106,965
and
-1 x -8,106,965 = 8,106,965
Notice both answers equal 8,106,965
With that explanation out of the way, let's continue. Next, we take the number 8,106,965 and divide it by 2:
8,106,965 ÷ 2 = 4,053,482.5
If the quotient is a whole number, then 2 and 4,053,482.5 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 | 8,106,965 | |
| -1 | -8,106,965 |
Now, we try dividing 8,106,965 by 3:
8,106,965 ÷ 3 = 2,702,321.6667
If the quotient is a whole number, then 3 and 2,702,321.6667 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 | 8,106,965 | |
| -1 | -8,106,965 |
Let's try dividing by 4:
8,106,965 ÷ 4 = 2,026,741.25
If the quotient is a whole number, then 4 and 2,026,741.25 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 | 8,106,965 | |
| -1 | 8,106,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 193 | 271 | 965 | 1,355 | 5,983 | 8,401 | 29,915 | 42,005 | 52,303 | 261,515 | 1,621,393 | 8,106,965 |
| -1 | -5 | -31 | -155 | -193 | -271 | -965 | -1,355 | -5,983 | -8,401 | -29,915 | -42,005 | -52,303 | -261,515 | -1,621,393 | -8,106,965 |
