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 16,825,445, 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 | 16,825,445 | |
| -1 | -16,825,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,825,445.
Example:
1 x 16,825,445 = 16,825,445
and
-1 x -16,825,445 = 16,825,445
Notice both answers equal 16,825,445
With that explanation out of the way, let's continue. Next, we take the number 16,825,445 and divide it by 2:
16,825,445 ÷ 2 = 8,412,722.5
If the quotient is a whole number, then 2 and 8,412,722.5 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 | 16,825,445 | |
| -1 | -16,825,445 |
Now, we try dividing 16,825,445 by 3:
16,825,445 ÷ 3 = 5,608,481.6667
If the quotient is a whole number, then 3 and 5,608,481.6667 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 | 16,825,445 | |
| -1 | -16,825,445 |
Let's try dividing by 4:
16,825,445 ÷ 4 = 4,206,361.25
If the quotient is a whole number, then 4 and 4,206,361.25 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 | 16,825,445 | |
| -1 | 16,825,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 36,979 | 184,895 | 258,853 | 480,727 | 1,294,265 | 2,403,635 | 3,365,089 | 16,825,445 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -36,979 | -184,895 | -258,853 | -480,727 | -1,294,265 | -2,403,635 | -3,365,089 | -16,825,445 |
