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 271,043,135, 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 | 271,043,135 | |
| -1 | -271,043,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,043,135.
Example:
1 x 271,043,135 = 271,043,135
and
-1 x -271,043,135 = 271,043,135
Notice both answers equal 271,043,135
With that explanation out of the way, let's continue. Next, we take the number 271,043,135 and divide it by 2:
271,043,135 ÷ 2 = 135,521,567.5
If the quotient is a whole number, then 2 and 135,521,567.5 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 | 271,043,135 | |
| -1 | -271,043,135 |
Now, we try dividing 271,043,135 by 3:
271,043,135 ÷ 3 = 90,347,711.6667
If the quotient is a whole number, then 3 and 90,347,711.6667 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 | 271,043,135 | |
| -1 | -271,043,135 |
Let's try dividing by 4:
271,043,135 ÷ 4 = 67,760,783.75
If the quotient is a whole number, then 4 and 67,760,783.75 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 | 271,043,135 | |
| -1 | 271,043,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 169,933 | 849,665 | 1,869,263 | 4,928,057 | 9,346,315 | 24,640,285 | 54,208,627 | 271,043,135 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -169,933 | -849,665 | -1,869,263 | -4,928,057 | -9,346,315 | -24,640,285 | -54,208,627 | -271,043,135 |
