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 16,681,595, 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 | 16,681,595 | |
| -1 | -16,681,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,681,595.
Example:
1 x 16,681,595 = 16,681,595
and
-1 x -16,681,595 = 16,681,595
Notice both answers equal 16,681,595
With that explanation out of the way, let's continue. Next, we take the number 16,681,595 and divide it by 2:
16,681,595 ÷ 2 = 8,340,797.5
If the quotient is a whole number, then 2 and 8,340,797.5 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 | 16,681,595 | |
| -1 | -16,681,595 |
Now, we try dividing 16,681,595 by 3:
16,681,595 ÷ 3 = 5,560,531.6667
If the quotient is a whole number, then 3 and 5,560,531.6667 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 | 16,681,595 | |
| -1 | -16,681,595 |
Let's try dividing by 4:
16,681,595 ÷ 4 = 4,170,398.75
If the quotient is a whole number, then 4 and 4,170,398.75 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 | 16,681,595 | |
| -1 | 16,681,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 73 | 365 | 511 | 2,555 | 6,529 | 32,645 | 45,703 | 228,515 | 476,617 | 2,383,085 | 3,336,319 | 16,681,595 |
| -1 | -5 | -7 | -35 | -73 | -365 | -511 | -2,555 | -6,529 | -32,645 | -45,703 | -228,515 | -476,617 | -2,383,085 | -3,336,319 | -16,681,595 |
