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 16,959,305, 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 | 16,959,305 | |
| -1 | -16,959,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,959,305.
Example:
1 x 16,959,305 = 16,959,305
and
-1 x -16,959,305 = 16,959,305
Notice both answers equal 16,959,305
With that explanation out of the way, let's continue. Next, we take the number 16,959,305 and divide it by 2:
16,959,305 ÷ 2 = 8,479,652.5
If the quotient is a whole number, then 2 and 8,479,652.5 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 | 16,959,305 | |
| -1 | -16,959,305 |
Now, we try dividing 16,959,305 by 3:
16,959,305 ÷ 3 = 5,653,101.6667
If the quotient is a whole number, then 3 and 5,653,101.6667 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 | 16,959,305 | |
| -1 | -16,959,305 |
Let's try dividing by 4:
16,959,305 ÷ 4 = 4,239,826.25
If the quotient is a whole number, then 4 and 4,239,826.25 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 | 16,959,305 | |
| -1 | 16,959,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 16,229 | 81,145 | 178,519 | 308,351 | 892,595 | 1,541,755 | 3,391,861 | 16,959,305 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -16,229 | -81,145 | -178,519 | -308,351 | -892,595 | -1,541,755 | -3,391,861 | -16,959,305 |
