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 271,684,081, 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 | 271,684,081 | |
| -1 | -271,684,081 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,684,081.
Example:
1 x 271,684,081 = 271,684,081
and
-1 x -271,684,081 = 271,684,081
Notice both answers equal 271,684,081
With that explanation out of the way, let's continue. Next, we take the number 271,684,081 and divide it by 2:
271,684,081 ÷ 2 = 135,842,040.5
If the quotient is a whole number, then 2 and 135,842,040.5 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 | 271,684,081 | |
| -1 | -271,684,081 |
Now, we try dividing 271,684,081 by 3:
271,684,081 ÷ 3 = 90,561,360.3333
If the quotient is a whole number, then 3 and 90,561,360.3333 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 | 271,684,081 | |
| -1 | -271,684,081 |
Let's try dividing by 4:
271,684,081 ÷ 4 = 67,921,020.25
If the quotient is a whole number, then 4 and 67,921,020.25 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 | 271,684,081 | |
| -1 | 271,684,081 |
If you did it right, you will end up with this table:
| 1 | 37 | 41 | 79 | 1,517 | 2,267 | 2,923 | 3,239 | 83,879 | 92,947 | 119,843 | 179,093 | 3,439,039 | 6,626,441 | 7,342,813 | 271,684,081 |
| -1 | -37 | -41 | -79 | -1,517 | -2,267 | -2,923 | -3,239 | -83,879 | -92,947 | -119,843 | -179,093 | -3,439,039 | -6,626,441 | -7,342,813 | -271,684,081 |
