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 10,404,845, 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 | 10,404,845 | |
| -1 | -10,404,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,404,845.
Example:
1 x 10,404,845 = 10,404,845
and
-1 x -10,404,845 = 10,404,845
Notice both answers equal 10,404,845
With that explanation out of the way, let's continue. Next, we take the number 10,404,845 and divide it by 2:
10,404,845 ÷ 2 = 5,202,422.5
If the quotient is a whole number, then 2 and 5,202,422.5 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 | 10,404,845 | |
| -1 | -10,404,845 |
Now, we try dividing 10,404,845 by 3:
10,404,845 ÷ 3 = 3,468,281.6667
If the quotient is a whole number, then 3 and 3,468,281.6667 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 | 10,404,845 | |
| -1 | -10,404,845 |
Let's try dividing by 4:
10,404,845 ÷ 4 = 2,601,211.25
If the quotient is a whole number, then 4 and 2,601,211.25 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 | 10,404,845 | |
| -1 | 10,404,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 139 | 695 | 1,361 | 1,529 | 6,805 | 7,645 | 14,971 | 74,855 | 189,179 | 945,895 | 2,080,969 | 10,404,845 |
| -1 | -5 | -11 | -55 | -139 | -695 | -1,361 | -1,529 | -6,805 | -7,645 | -14,971 | -74,855 | -189,179 | -945,895 | -2,080,969 | -10,404,845 |
