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 6,607,165, 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 | 6,607,165 | |
| -1 | -6,607,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,607,165.
Example:
1 x 6,607,165 = 6,607,165
and
-1 x -6,607,165 = 6,607,165
Notice both answers equal 6,607,165
With that explanation out of the way, let's continue. Next, we take the number 6,607,165 and divide it by 2:
6,607,165 ÷ 2 = 3,303,582.5
If the quotient is a whole number, then 2 and 3,303,582.5 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 | 6,607,165 | |
| -1 | -6,607,165 |
Now, we try dividing 6,607,165 by 3:
6,607,165 ÷ 3 = 2,202,388.3333
If the quotient is a whole number, then 3 and 2,202,388.3333 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 | 6,607,165 | |
| -1 | -6,607,165 |
Let's try dividing by 4:
6,607,165 ÷ 4 = 1,651,791.25
If the quotient is a whole number, then 4 and 1,651,791.25 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 | 6,607,165 | |
| -1 | 6,607,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 79 | 215 | 389 | 395 | 1,945 | 3,397 | 16,727 | 16,985 | 30,731 | 83,635 | 153,655 | 1,321,433 | 6,607,165 |
| -1 | -5 | -43 | -79 | -215 | -389 | -395 | -1,945 | -3,397 | -16,727 | -16,985 | -30,731 | -83,635 | -153,655 | -1,321,433 | -6,607,165 |
