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 8,103,407, 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 | 8,103,407 | |
| -1 | -8,103,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,103,407.
Example:
1 x 8,103,407 = 8,103,407
and
-1 x -8,103,407 = 8,103,407
Notice both answers equal 8,103,407
With that explanation out of the way, let's continue. Next, we take the number 8,103,407 and divide it by 2:
8,103,407 ÷ 2 = 4,051,703.5
If the quotient is a whole number, then 2 and 4,051,703.5 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 | 8,103,407 | |
| -1 | -8,103,407 |
Now, we try dividing 8,103,407 by 3:
8,103,407 ÷ 3 = 2,701,135.6667
If the quotient is a whole number, then 3 and 2,701,135.6667 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 | 8,103,407 | |
| -1 | -8,103,407 |
Let's try dividing by 4:
8,103,407 ÷ 4 = 2,025,851.75
If the quotient is a whole number, then 4 and 2,025,851.75 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 | 8,103,407 | |
| -1 | 8,103,407 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 37 | 221 | 481 | 629 | 991 | 8,177 | 12,883 | 16,847 | 36,667 | 219,011 | 476,671 | 623,339 | 8,103,407 |
| -1 | -13 | -17 | -37 | -221 | -481 | -629 | -991 | -8,177 | -12,883 | -16,847 | -36,667 | -219,011 | -476,671 | -623,339 | -8,103,407 |
