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 271,036,505, 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 | 271,036,505 | |
| -1 | -271,036,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,036,505.
Example:
1 x 271,036,505 = 271,036,505
and
-1 x -271,036,505 = 271,036,505
Notice both answers equal 271,036,505
With that explanation out of the way, let's continue. Next, we take the number 271,036,505 and divide it by 2:
271,036,505 ÷ 2 = 135,518,252.5
If the quotient is a whole number, then 2 and 135,518,252.5 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 | 271,036,505 | |
| -1 | -271,036,505 |
Now, we try dividing 271,036,505 by 3:
271,036,505 ÷ 3 = 90,345,501.6667
If the quotient is a whole number, then 3 and 90,345,501.6667 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 | 271,036,505 | |
| -1 | -271,036,505 |
Let's try dividing by 4:
271,036,505 ÷ 4 = 67,759,126.25
If the quotient is a whole number, then 4 and 67,759,126.25 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 | 271,036,505 | |
| -1 | 271,036,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 173 | 431 | 727 | 865 | 2,155 | 3,635 | 74,563 | 125,771 | 313,337 | 372,815 | 628,855 | 1,566,685 | 54,207,301 | 271,036,505 |
| -1 | -5 | -173 | -431 | -727 | -865 | -2,155 | -3,635 | -74,563 | -125,771 | -313,337 | -372,815 | -628,855 | -1,566,685 | -54,207,301 | -271,036,505 |
