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 271,055,375, 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 | 271,055,375 | |
| -1 | -271,055,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,055,375.
Example:
1 x 271,055,375 = 271,055,375
and
-1 x -271,055,375 = 271,055,375
Notice both answers equal 271,055,375
With that explanation out of the way, let's continue. Next, we take the number 271,055,375 and divide it by 2:
271,055,375 ÷ 2 = 135,527,687.5
If the quotient is a whole number, then 2 and 135,527,687.5 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 | 271,055,375 | |
| -1 | -271,055,375 |
Now, we try dividing 271,055,375 by 3:
271,055,375 ÷ 3 = 90,351,791.6667
If the quotient is a whole number, then 3 and 90,351,791.6667 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 | 271,055,375 | |
| -1 | -271,055,375 |
Let's try dividing by 4:
271,055,375 ÷ 4 = 67,763,843.75
If the quotient is a whole number, then 4 and 67,763,843.75 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 | 271,055,375 | |
| -1 | 271,055,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 131 | 655 | 3,275 | 16,375 | 16,553 | 82,765 | 413,825 | 2,069,125 | 2,168,443 | 10,842,215 | 54,211,075 | 271,055,375 |
| -1 | -5 | -25 | -125 | -131 | -655 | -3,275 | -16,375 | -16,553 | -82,765 | -413,825 | -2,069,125 | -2,168,443 | -10,842,215 | -54,211,075 | -271,055,375 |
