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 27,125,255, 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 | 27,125,255 | |
| -1 | -27,125,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,125,255.
Example:
1 x 27,125,255 = 27,125,255
and
-1 x -27,125,255 = 27,125,255
Notice both answers equal 27,125,255
With that explanation out of the way, let's continue. Next, we take the number 27,125,255 and divide it by 2:
27,125,255 ÷ 2 = 13,562,627.5
If the quotient is a whole number, then 2 and 13,562,627.5 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 | 27,125,255 | |
| -1 | -27,125,255 |
Now, we try dividing 27,125,255 by 3:
27,125,255 ÷ 3 = 9,041,751.6667
If the quotient is a whole number, then 3 and 9,041,751.6667 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 | 27,125,255 | |
| -1 | -27,125,255 |
Let's try dividing by 4:
27,125,255 ÷ 4 = 6,781,313.75
If the quotient is a whole number, then 4 and 6,781,313.75 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 | 27,125,255 | |
| -1 | 27,125,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 37 | 95 | 185 | 703 | 3,515 | 7,717 | 38,585 | 146,623 | 285,529 | 733,115 | 1,427,645 | 5,425,051 | 27,125,255 |
| -1 | -5 | -19 | -37 | -95 | -185 | -703 | -3,515 | -7,717 | -38,585 | -146,623 | -285,529 | -733,115 | -1,427,645 | -5,425,051 | -27,125,255 |
