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 16,330,325, 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 | 16,330,325 | |
| -1 | -16,330,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,330,325.
Example:
1 x 16,330,325 = 16,330,325
and
-1 x -16,330,325 = 16,330,325
Notice both answers equal 16,330,325
With that explanation out of the way, let's continue. Next, we take the number 16,330,325 and divide it by 2:
16,330,325 ÷ 2 = 8,165,162.5
If the quotient is a whole number, then 2 and 8,165,162.5 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 | 16,330,325 | |
| -1 | -16,330,325 |
Now, we try dividing 16,330,325 by 3:
16,330,325 ÷ 3 = 5,443,441.6667
If the quotient is a whole number, then 3 and 5,443,441.6667 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 | 16,330,325 | |
| -1 | -16,330,325 |
Let's try dividing by 4:
16,330,325 ÷ 4 = 4,082,581.25
If the quotient is a whole number, then 4 and 4,082,581.25 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 | 16,330,325 | |
| -1 | 16,330,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 43 | 55 | 215 | 275 | 473 | 1,075 | 1,381 | 2,365 | 6,905 | 11,825 | 15,191 | 34,525 | 59,383 | 75,955 | 296,915 | 379,775 | 653,213 | 1,484,575 | 3,266,065 | 16,330,325 |
| -1 | -5 | -11 | -25 | -43 | -55 | -215 | -275 | -473 | -1,075 | -1,381 | -2,365 | -6,905 | -11,825 | -15,191 | -34,525 | -59,383 | -75,955 | -296,915 | -379,775 | -653,213 | -1,484,575 | -3,266,065 | -16,330,325 |
