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 14,205,125, 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 | 14,205,125 | |
| -1 | -14,205,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,205,125.
Example:
1 x 14,205,125 = 14,205,125
and
-1 x -14,205,125 = 14,205,125
Notice both answers equal 14,205,125
With that explanation out of the way, let's continue. Next, we take the number 14,205,125 and divide it by 2:
14,205,125 ÷ 2 = 7,102,562.5
If the quotient is a whole number, then 2 and 7,102,562.5 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 | 14,205,125 | |
| -1 | -14,205,125 |
Now, we try dividing 14,205,125 by 3:
14,205,125 ÷ 3 = 4,735,041.6667
If the quotient is a whole number, then 3 and 4,735,041.6667 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 | 14,205,125 | |
| -1 | -14,205,125 |
Let's try dividing by 4:
14,205,125 ÷ 4 = 3,551,281.25
If the quotient is a whole number, then 4 and 3,551,281.25 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 | 14,205,125 | |
| -1 | 14,205,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 1,375 | 10,331 | 51,655 | 113,641 | 258,275 | 568,205 | 1,291,375 | 2,841,025 | 14,205,125 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -1,375 | -10,331 | -51,655 | -113,641 | -258,275 | -568,205 | -1,291,375 | -2,841,025 | -14,205,125 |
