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 27,084,125, 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 | 27,084,125 | |
| -1 | -27,084,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,084,125.
Example:
1 x 27,084,125 = 27,084,125
and
-1 x -27,084,125 = 27,084,125
Notice both answers equal 27,084,125
With that explanation out of the way, let's continue. Next, we take the number 27,084,125 and divide it by 2:
27,084,125 ÷ 2 = 13,542,062.5
If the quotient is a whole number, then 2 and 13,542,062.5 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 | 27,084,125 | |
| -1 | -27,084,125 |
Now, we try dividing 27,084,125 by 3:
27,084,125 ÷ 3 = 9,028,041.6667
If the quotient is a whole number, then 3 and 9,028,041.6667 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 | 27,084,125 | |
| -1 | -27,084,125 |
Let's try dividing by 4:
27,084,125 ÷ 4 = 6,771,031.25
If the quotient is a whole number, then 4 and 6,771,031.25 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 | 27,084,125 | |
| -1 | 27,084,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 389 | 557 | 1,945 | 2,785 | 9,725 | 13,925 | 48,625 | 69,625 | 216,673 | 1,083,365 | 5,416,825 | 27,084,125 |
| -1 | -5 | -25 | -125 | -389 | -557 | -1,945 | -2,785 | -9,725 | -13,925 | -48,625 | -69,625 | -216,673 | -1,083,365 | -5,416,825 | -27,084,125 |
