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 6,615,325, 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 | 6,615,325 | |
| -1 | -6,615,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,615,325.
Example:
1 x 6,615,325 = 6,615,325
and
-1 x -6,615,325 = 6,615,325
Notice both answers equal 6,615,325
With that explanation out of the way, let's continue. Next, we take the number 6,615,325 and divide it by 2:
6,615,325 ÷ 2 = 3,307,662.5
If the quotient is a whole number, then 2 and 3,307,662.5 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 | 6,615,325 | |
| -1 | -6,615,325 |
Now, we try dividing 6,615,325 by 3:
6,615,325 ÷ 3 = 2,205,108.3333
If the quotient is a whole number, then 3 and 2,205,108.3333 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 | 6,615,325 | |
| -1 | -6,615,325 |
Let's try dividing by 4:
6,615,325 ÷ 4 = 1,653,831.25
If the quotient is a whole number, then 4 and 1,653,831.25 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 | 6,615,325 | |
| -1 | 6,615,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 361 | 475 | 733 | 1,805 | 3,665 | 9,025 | 13,927 | 18,325 | 69,635 | 264,613 | 348,175 | 1,323,065 | 6,615,325 |
| -1 | -5 | -19 | -25 | -95 | -361 | -475 | -733 | -1,805 | -3,665 | -9,025 | -13,927 | -18,325 | -69,635 | -264,613 | -348,175 | -1,323,065 | -6,615,325 |
