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 271,136,015, 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 | 271,136,015 | |
| -1 | -271,136,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,136,015.
Example:
1 x 271,136,015 = 271,136,015
and
-1 x -271,136,015 = 271,136,015
Notice both answers equal 271,136,015
With that explanation out of the way, let's continue. Next, we take the number 271,136,015 and divide it by 2:
271,136,015 ÷ 2 = 135,568,007.5
If the quotient is a whole number, then 2 and 135,568,007.5 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 | 271,136,015 | |
| -1 | -271,136,015 |
Now, we try dividing 271,136,015 by 3:
271,136,015 ÷ 3 = 90,378,671.6667
If the quotient is a whole number, then 3 and 90,378,671.6667 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 | 271,136,015 | |
| -1 | -271,136,015 |
Let's try dividing by 4:
271,136,015 ÷ 4 = 67,784,003.75
If the quotient is a whole number, then 4 and 67,784,003.75 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 | 271,136,015 | |
| -1 | 271,136,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 137 | 505 | 685 | 3,919 | 13,837 | 19,595 | 69,185 | 395,819 | 536,903 | 1,979,095 | 2,684,515 | 54,227,203 | 271,136,015 |
| -1 | -5 | -101 | -137 | -505 | -685 | -3,919 | -13,837 | -19,595 | -69,185 | -395,819 | -536,903 | -1,979,095 | -2,684,515 | -54,227,203 | -271,136,015 |
