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 27,004,367, 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 | 27,004,367 | |
| -1 | -27,004,367 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,004,367.
Example:
1 x 27,004,367 = 27,004,367
and
-1 x -27,004,367 = 27,004,367
Notice both answers equal 27,004,367
With that explanation out of the way, let's continue. Next, we take the number 27,004,367 and divide it by 2:
27,004,367 ÷ 2 = 13,502,183.5
If the quotient is a whole number, then 2 and 13,502,183.5 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 | 27,004,367 | |
| -1 | -27,004,367 |
Now, we try dividing 27,004,367 by 3:
27,004,367 ÷ 3 = 9,001,455.6667
If the quotient is a whole number, then 3 and 9,001,455.6667 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 | 27,004,367 | |
| -1 | -27,004,367 |
Let's try dividing by 4:
27,004,367 ÷ 4 = 6,751,091.75
If the quotient is a whole number, then 4 and 6,751,091.75 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 | 27,004,367 | |
| -1 | 27,004,367 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 193 | 229 | 611 | 2,509 | 2,977 | 9,071 | 10,763 | 44,197 | 117,923 | 139,919 | 574,561 | 2,077,259 | 27,004,367 |
| -1 | -13 | -47 | -193 | -229 | -611 | -2,509 | -2,977 | -9,071 | -10,763 | -44,197 | -117,923 | -139,919 | -574,561 | -2,077,259 | -27,004,367 |
