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 9,909,935, 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 | 9,909,935 | |
| -1 | -9,909,935 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,909,935.
Example:
1 x 9,909,935 = 9,909,935
and
-1 x -9,909,935 = 9,909,935
Notice both answers equal 9,909,935
With that explanation out of the way, let's continue. Next, we take the number 9,909,935 and divide it by 2:
9,909,935 ÷ 2 = 4,954,967.5
If the quotient is a whole number, then 2 and 4,954,967.5 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 | 9,909,935 | |
| -1 | -9,909,935 |
Now, we try dividing 9,909,935 by 3:
9,909,935 ÷ 3 = 3,303,311.6667
If the quotient is a whole number, then 3 and 3,303,311.6667 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 | 9,909,935 | |
| -1 | -9,909,935 |
Let's try dividing by 4:
9,909,935 ÷ 4 = 2,477,483.75
If the quotient is a whole number, then 4 and 2,477,483.75 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 | 9,909,935 | |
| -1 | 9,909,935 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 59 | 295 | 413 | 2,065 | 4,799 | 23,995 | 33,593 | 167,965 | 283,141 | 1,415,705 | 1,981,987 | 9,909,935 |
| -1 | -5 | -7 | -35 | -59 | -295 | -413 | -2,065 | -4,799 | -23,995 | -33,593 | -167,965 | -283,141 | -1,415,705 | -1,981,987 | -9,909,935 |
