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 16,440,325, 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 | 16,440,325 | |
| -1 | -16,440,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,440,325.
Example:
1 x 16,440,325 = 16,440,325
and
-1 x -16,440,325 = 16,440,325
Notice both answers equal 16,440,325
With that explanation out of the way, let's continue. Next, we take the number 16,440,325 and divide it by 2:
16,440,325 ÷ 2 = 8,220,162.5
If the quotient is a whole number, then 2 and 8,220,162.5 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 | 16,440,325 | |
| -1 | -16,440,325 |
Now, we try dividing 16,440,325 by 3:
16,440,325 ÷ 3 = 5,480,108.3333
If the quotient is a whole number, then 3 and 5,480,108.3333 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 | 16,440,325 | |
| -1 | -16,440,325 |
Let's try dividing by 4:
16,440,325 ÷ 4 = 4,110,081.25
If the quotient is a whole number, then 4 and 4,110,081.25 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 | 16,440,325 | |
| -1 | 16,440,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 191 | 275 | 313 | 955 | 1,565 | 2,101 | 3,443 | 4,775 | 7,825 | 10,505 | 17,215 | 52,525 | 59,783 | 86,075 | 298,915 | 657,613 | 1,494,575 | 3,288,065 | 16,440,325 |
| -1 | -5 | -11 | -25 | -55 | -191 | -275 | -313 | -955 | -1,565 | -2,101 | -3,443 | -4,775 | -7,825 | -10,505 | -17,215 | -52,525 | -59,783 | -86,075 | -298,915 | -657,613 | -1,494,575 | -3,288,065 | -16,440,325 |
