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 6,607,315, 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 | 6,607,315 | |
| -1 | -6,607,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,607,315.
Example:
1 x 6,607,315 = 6,607,315
and
-1 x -6,607,315 = 6,607,315
Notice both answers equal 6,607,315
With that explanation out of the way, let's continue. Next, we take the number 6,607,315 and divide it by 2:
6,607,315 ÷ 2 = 3,303,657.5
If the quotient is a whole number, then 2 and 3,303,657.5 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 | 6,607,315 | |
| -1 | -6,607,315 |
Now, we try dividing 6,607,315 by 3:
6,607,315 ÷ 3 = 2,202,438.3333
If the quotient is a whole number, then 3 and 2,202,438.3333 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 | 6,607,315 | |
| -1 | -6,607,315 |
Let's try dividing by 4:
6,607,315 ÷ 4 = 1,651,828.75
If the quotient is a whole number, then 4 and 1,651,828.75 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 | 6,607,315 | |
| -1 | 6,607,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 9,241 | 46,205 | 101,651 | 120,133 | 508,255 | 600,665 | 1,321,463 | 6,607,315 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -9,241 | -46,205 | -101,651 | -120,133 | -508,255 | -600,665 | -1,321,463 | -6,607,315 |
