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 8,107,435, 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 | 8,107,435 | |
| -1 | -8,107,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,107,435.
Example:
1 x 8,107,435 = 8,107,435
and
-1 x -8,107,435 = 8,107,435
Notice both answers equal 8,107,435
With that explanation out of the way, let's continue. Next, we take the number 8,107,435 and divide it by 2:
8,107,435 ÷ 2 = 4,053,717.5
If the quotient is a whole number, then 2 and 4,053,717.5 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 | 8,107,435 | |
| -1 | -8,107,435 |
Now, we try dividing 8,107,435 by 3:
8,107,435 ÷ 3 = 2,702,478.3333
If the quotient is a whole number, then 3 and 2,702,478.3333 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 | 8,107,435 | |
| -1 | -8,107,435 |
Let's try dividing by 4:
8,107,435 ÷ 4 = 2,026,858.75
If the quotient is a whole number, then 4 and 2,026,858.75 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 | 8,107,435 | |
| -1 | 8,107,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 5,387 | 26,935 | 37,709 | 188,545 | 231,641 | 1,158,205 | 1,621,487 | 8,107,435 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -5,387 | -26,935 | -37,709 | -188,545 | -231,641 | -1,158,205 | -1,621,487 | -8,107,435 |
