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 271,341,665, 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 | 271,341,665 | |
| -1 | -271,341,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,341,665.
Example:
1 x 271,341,665 = 271,341,665
and
-1 x -271,341,665 = 271,341,665
Notice both answers equal 271,341,665
With that explanation out of the way, let's continue. Next, we take the number 271,341,665 and divide it by 2:
271,341,665 ÷ 2 = 135,670,832.5
If the quotient is a whole number, then 2 and 135,670,832.5 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 | 271,341,665 | |
| -1 | -271,341,665 |
Now, we try dividing 271,341,665 by 3:
271,341,665 ÷ 3 = 90,447,221.6667
If the quotient is a whole number, then 3 and 90,447,221.6667 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 | 271,341,665 | |
| -1 | -271,341,665 |
Let's try dividing by 4:
271,341,665 ÷ 4 = 67,835,416.25
If the quotient is a whole number, then 4 and 67,835,416.25 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 | 271,341,665 | |
| -1 | 271,341,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 149 | 245 | 745 | 1,043 | 5,215 | 7,301 | 7,433 | 36,505 | 37,165 | 52,031 | 260,155 | 364,217 | 1,107,517 | 1,821,085 | 5,537,585 | 7,752,619 | 38,763,095 | 54,268,333 | 271,341,665 |
| -1 | -5 | -7 | -35 | -49 | -149 | -245 | -745 | -1,043 | -5,215 | -7,301 | -7,433 | -36,505 | -37,165 | -52,031 | -260,155 | -364,217 | -1,107,517 | -1,821,085 | -5,537,585 | -7,752,619 | -38,763,095 | -54,268,333 | -271,341,665 |
