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 16,863,595, 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 | 16,863,595 | |
| -1 | -16,863,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,863,595.
Example:
1 x 16,863,595 = 16,863,595
and
-1 x -16,863,595 = 16,863,595
Notice both answers equal 16,863,595
With that explanation out of the way, let's continue. Next, we take the number 16,863,595 and divide it by 2:
16,863,595 ÷ 2 = 8,431,797.5
If the quotient is a whole number, then 2 and 8,431,797.5 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 | 16,863,595 | |
| -1 | -16,863,595 |
Now, we try dividing 16,863,595 by 3:
16,863,595 ÷ 3 = 5,621,198.3333
If the quotient is a whole number, then 3 and 5,621,198.3333 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 | 16,863,595 | |
| -1 | -16,863,595 |
Let's try dividing by 4:
16,863,595 ÷ 4 = 4,215,898.75
If the quotient is a whole number, then 4 and 4,215,898.75 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 | 16,863,595 | |
| -1 | 16,863,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 9,833 | 49,165 | 68,831 | 344,155 | 481,817 | 2,409,085 | 3,372,719 | 16,863,595 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -9,833 | -49,165 | -68,831 | -344,155 | -481,817 | -2,409,085 | -3,372,719 | -16,863,595 |
