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 271,027,285, 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 | 271,027,285 | |
| -1 | -271,027,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,027,285.
Example:
1 x 271,027,285 = 271,027,285
and
-1 x -271,027,285 = 271,027,285
Notice both answers equal 271,027,285
With that explanation out of the way, let's continue. Next, we take the number 271,027,285 and divide it by 2:
271,027,285 ÷ 2 = 135,513,642.5
If the quotient is a whole number, then 2 and 135,513,642.5 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 | 271,027,285 | |
| -1 | -271,027,285 |
Now, we try dividing 271,027,285 by 3:
271,027,285 ÷ 3 = 90,342,428.3333
If the quotient is a whole number, then 3 and 90,342,428.3333 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 | 271,027,285 | |
| -1 | -271,027,285 |
Let's try dividing by 4:
271,027,285 ÷ 4 = 67,756,821.25
If the quotient is a whole number, then 4 and 67,756,821.25 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 | 271,027,285 | |
| -1 | 271,027,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 887 | 2,657 | 4,435 | 13,285 | 20,401 | 61,111 | 102,005 | 305,555 | 2,356,759 | 11,783,795 | 54,205,457 | 271,027,285 |
| -1 | -5 | -23 | -115 | -887 | -2,657 | -4,435 | -13,285 | -20,401 | -61,111 | -102,005 | -305,555 | -2,356,759 | -11,783,795 | -54,205,457 | -271,027,285 |
