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 8,373,715, 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 | 8,373,715 | |
| -1 | -8,373,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,373,715.
Example:
1 x 8,373,715 = 8,373,715
and
-1 x -8,373,715 = 8,373,715
Notice both answers equal 8,373,715
With that explanation out of the way, let's continue. Next, we take the number 8,373,715 and divide it by 2:
8,373,715 ÷ 2 = 4,186,857.5
If the quotient is a whole number, then 2 and 4,186,857.5 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 | 8,373,715 | |
| -1 | -8,373,715 |
Now, we try dividing 8,373,715 by 3:
8,373,715 ÷ 3 = 2,791,238.3333
If the quotient is a whole number, then 3 and 2,791,238.3333 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 | 8,373,715 | |
| -1 | -8,373,715 |
Let's try dividing by 4:
8,373,715 ÷ 4 = 2,093,428.75
If the quotient is a whole number, then 4 and 2,093,428.75 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 | 8,373,715 | |
| -1 | 8,373,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 419 | 571 | 2,095 | 2,855 | 2,933 | 3,997 | 14,665 | 19,985 | 239,249 | 1,196,245 | 1,674,743 | 8,373,715 |
| -1 | -5 | -7 | -35 | -419 | -571 | -2,095 | -2,855 | -2,933 | -3,997 | -14,665 | -19,985 | -239,249 | -1,196,245 | -1,674,743 | -8,373,715 |
