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 271,377,205, 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 | 271,377,205 | |
| -1 | -271,377,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,377,205.
Example:
1 x 271,377,205 = 271,377,205
and
-1 x -271,377,205 = 271,377,205
Notice both answers equal 271,377,205
With that explanation out of the way, let's continue. Next, we take the number 271,377,205 and divide it by 2:
271,377,205 ÷ 2 = 135,688,602.5
If the quotient is a whole number, then 2 and 135,688,602.5 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 | 271,377,205 | |
| -1 | -271,377,205 |
Now, we try dividing 271,377,205 by 3:
271,377,205 ÷ 3 = 90,459,068.3333
If the quotient is a whole number, then 3 and 90,459,068.3333 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 | 271,377,205 | |
| -1 | -271,377,205 |
Let's try dividing by 4:
271,377,205 ÷ 4 = 67,844,301.25
If the quotient is a whole number, then 4 and 67,844,301.25 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 | 271,377,205 | |
| -1 | 271,377,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 290,243 | 1,451,215 | 3,192,673 | 4,934,131 | 15,963,365 | 24,670,655 | 54,275,441 | 271,377,205 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -290,243 | -1,451,215 | -3,192,673 | -4,934,131 | -15,963,365 | -24,670,655 | -54,275,441 | -271,377,205 |
