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 9,404,447, 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 | 9,404,447 | |
| -1 | -9,404,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,404,447.
Example:
1 x 9,404,447 = 9,404,447
and
-1 x -9,404,447 = 9,404,447
Notice both answers equal 9,404,447
With that explanation out of the way, let's continue. Next, we take the number 9,404,447 and divide it by 2:
9,404,447 ÷ 2 = 4,702,223.5
If the quotient is a whole number, then 2 and 4,702,223.5 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 | 9,404,447 | |
| -1 | -9,404,447 |
Now, we try dividing 9,404,447 by 3:
9,404,447 ÷ 3 = 3,134,815.6667
If the quotient is a whole number, then 3 and 3,134,815.6667 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 | 9,404,447 | |
| -1 | -9,404,447 |
Let's try dividing by 4:
9,404,447 ÷ 4 = 2,351,111.75
If the quotient is a whole number, then 4 and 2,351,111.75 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 | 9,404,447 | |
| -1 | 9,404,447 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 71 | 299 | 443 | 923 | 1,633 | 5,759 | 10,189 | 21,229 | 31,453 | 132,457 | 408,889 | 723,419 | 9,404,447 |
| -1 | -13 | -23 | -71 | -299 | -443 | -923 | -1,633 | -5,759 | -10,189 | -21,229 | -31,453 | -132,457 | -408,889 | -723,419 | -9,404,447 |
