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 271,053,055, 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 | 271,053,055 | |
| -1 | -271,053,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,053,055.
Example:
1 x 271,053,055 = 271,053,055
and
-1 x -271,053,055 = 271,053,055
Notice both answers equal 271,053,055
With that explanation out of the way, let's continue. Next, we take the number 271,053,055 and divide it by 2:
271,053,055 ÷ 2 = 135,526,527.5
If the quotient is a whole number, then 2 and 135,526,527.5 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 | 271,053,055 | |
| -1 | -271,053,055 |
Now, we try dividing 271,053,055 by 3:
271,053,055 ÷ 3 = 90,351,018.3333
If the quotient is a whole number, then 3 and 90,351,018.3333 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 | 271,053,055 | |
| -1 | -271,053,055 |
Let's try dividing by 4:
271,053,055 ÷ 4 = 67,763,263.75
If the quotient is a whole number, then 4 and 67,763,263.75 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 | 271,053,055 | |
| -1 | 271,053,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 49 | 65 | 91 | 245 | 455 | 637 | 3,185 | 85,103 | 425,515 | 595,721 | 1,106,339 | 2,978,605 | 4,170,047 | 5,531,695 | 7,744,373 | 20,850,235 | 38,721,865 | 54,210,611 | 271,053,055 |
| -1 | -5 | -7 | -13 | -35 | -49 | -65 | -91 | -245 | -455 | -637 | -3,185 | -85,103 | -425,515 | -595,721 | -1,106,339 | -2,978,605 | -4,170,047 | -5,531,695 | -7,744,373 | -20,850,235 | -38,721,865 | -54,210,611 | -271,053,055 |
