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 16,016,105, 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 | 16,016,105 | |
| -1 | -16,016,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,016,105.
Example:
1 x 16,016,105 = 16,016,105
and
-1 x -16,016,105 = 16,016,105
Notice both answers equal 16,016,105
With that explanation out of the way, let's continue. Next, we take the number 16,016,105 and divide it by 2:
16,016,105 ÷ 2 = 8,008,052.5
If the quotient is a whole number, then 2 and 8,008,052.5 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 | 16,016,105 | |
| -1 | -16,016,105 |
Now, we try dividing 16,016,105 by 3:
16,016,105 ÷ 3 = 5,338,701.6667
If the quotient is a whole number, then 3 and 5,338,701.6667 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 | 16,016,105 | |
| -1 | -16,016,105 |
Let's try dividing by 4:
16,016,105 ÷ 4 = 4,004,026.25
If the quotient is a whole number, then 4 and 4,004,026.25 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 | 16,016,105 | |
| -1 | 16,016,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 193 | 965 | 1,351 | 2,371 | 6,755 | 11,855 | 16,597 | 82,985 | 457,603 | 2,288,015 | 3,203,221 | 16,016,105 |
| -1 | -5 | -7 | -35 | -193 | -965 | -1,351 | -2,371 | -6,755 | -11,855 | -16,597 | -82,985 | -457,603 | -2,288,015 | -3,203,221 | -16,016,105 |
