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 104,404,405, 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 | 104,404,405 | |
| -1 | -104,404,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,404,405.
Example:
1 x 104,404,405 = 104,404,405
and
-1 x -104,404,405 = 104,404,405
Notice both answers equal 104,404,405
With that explanation out of the way, let's continue. Next, we take the number 104,404,405 and divide it by 2:
104,404,405 ÷ 2 = 52,202,202.5
If the quotient is a whole number, then 2 and 52,202,202.5 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 | 104,404,405 | |
| -1 | -104,404,405 |
Now, we try dividing 104,404,405 by 3:
104,404,405 ÷ 3 = 34,801,468.3333
If the quotient is a whole number, then 3 and 34,801,468.3333 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 | 104,404,405 | |
| -1 | -104,404,405 |
Let's try dividing by 4:
104,404,405 ÷ 4 = 26,101,101.25
If the quotient is a whole number, then 4 and 26,101,101.25 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 | 104,404,405 | |
| -1 | 104,404,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 103 | 515 | 721 | 3,605 | 28,961 | 144,805 | 202,727 | 1,013,635 | 2,982,983 | 14,914,915 | 20,880,881 | 104,404,405 |
| -1 | -5 | -7 | -35 | -103 | -515 | -721 | -3,605 | -28,961 | -144,805 | -202,727 | -1,013,635 | -2,982,983 | -14,914,915 | -20,880,881 | -104,404,405 |
