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 16,320,935, 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 | 16,320,935 | |
| -1 | -16,320,935 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,320,935.
Example:
1 x 16,320,935 = 16,320,935
and
-1 x -16,320,935 = 16,320,935
Notice both answers equal 16,320,935
With that explanation out of the way, let's continue. Next, we take the number 16,320,935 and divide it by 2:
16,320,935 ÷ 2 = 8,160,467.5
If the quotient is a whole number, then 2 and 8,160,467.5 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 | 16,320,935 | |
| -1 | -16,320,935 |
Now, we try dividing 16,320,935 by 3:
16,320,935 ÷ 3 = 5,440,311.6667
If the quotient is a whole number, then 3 and 5,440,311.6667 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 | 16,320,935 | |
| -1 | -16,320,935 |
Let's try dividing by 4:
16,320,935 ÷ 4 = 4,080,233.75
If the quotient is a whole number, then 4 and 4,080,233.75 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 | 16,320,935 | |
| -1 | 16,320,935 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 157 | 785 | 1,223 | 2,669 | 6,115 | 13,345 | 20,791 | 103,955 | 192,011 | 960,055 | 3,264,187 | 16,320,935 |
| -1 | -5 | -17 | -85 | -157 | -785 | -1,223 | -2,669 | -6,115 | -13,345 | -20,791 | -103,955 | -192,011 | -960,055 | -3,264,187 | -16,320,935 |
