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 27,750,775, 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 | 27,750,775 | |
| -1 | -27,750,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 27,750,775.
Example:
1 x 27,750,775 = 27,750,775
and
-1 x -27,750,775 = 27,750,775
Notice both answers equal 27,750,775
With that explanation out of the way, let's continue. Next, we take the number 27,750,775 and divide it by 2:
27,750,775 ÷ 2 = 13,875,387.5
If the quotient is a whole number, then 2 and 13,875,387.5 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 | 27,750,775 | |
| -1 | -27,750,775 |
Now, we try dividing 27,750,775 by 3:
27,750,775 ÷ 3 = 9,250,258.3333
If the quotient is a whole number, then 3 and 9,250,258.3333 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 | 27,750,775 | |
| -1 | -27,750,775 |
Let's try dividing by 4:
27,750,775 ÷ 4 = 6,937,693.75
If the quotient is a whole number, then 4 and 6,937,693.75 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 | 27,750,775 | |
| -1 | 27,750,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 103 | 325 | 515 | 829 | 1,339 | 2,575 | 4,145 | 6,695 | 10,777 | 20,725 | 33,475 | 53,885 | 85,387 | 269,425 | 426,935 | 1,110,031 | 2,134,675 | 5,550,155 | 27,750,775 |
| -1 | -5 | -13 | -25 | -65 | -103 | -325 | -515 | -829 | -1,339 | -2,575 | -4,145 | -6,695 | -10,777 | -20,725 | -33,475 | -53,885 | -85,387 | -269,425 | -426,935 | -1,110,031 | -2,134,675 | -5,550,155 | -27,750,775 |
