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 16,825,013, 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 | 16,825,013 | |
| -1 | -16,825,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,825,013.
Example:
1 x 16,825,013 = 16,825,013
and
-1 x -16,825,013 = 16,825,013
Notice both answers equal 16,825,013
With that explanation out of the way, let's continue. Next, we take the number 16,825,013 and divide it by 2:
16,825,013 ÷ 2 = 8,412,506.5
If the quotient is a whole number, then 2 and 8,412,506.5 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 | 16,825,013 | |
| -1 | -16,825,013 |
Now, we try dividing 16,825,013 by 3:
16,825,013 ÷ 3 = 5,608,337.6667
If the quotient is a whole number, then 3 and 5,608,337.6667 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 | 16,825,013 | |
| -1 | -16,825,013 |
Let's try dividing by 4:
16,825,013 ÷ 4 = 4,206,253.25
If the quotient is a whole number, then 4 and 4,206,253.25 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 | 16,825,013 | |
| -1 | 16,825,013 |
If you did it right, you will end up with this table:
| 1 | 19 | 47 | 83 | 227 | 893 | 1,577 | 3,901 | 4,313 | 10,669 | 18,841 | 74,119 | 202,711 | 357,979 | 885,527 | 16,825,013 |
| -1 | -19 | -47 | -83 | -227 | -893 | -1,577 | -3,901 | -4,313 | -10,669 | -18,841 | -74,119 | -202,711 | -357,979 | -885,527 | -16,825,013 |
