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 271,185,215, 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 | 271,185,215 | |
| -1 | -271,185,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,185,215.
Example:
1 x 271,185,215 = 271,185,215
and
-1 x -271,185,215 = 271,185,215
Notice both answers equal 271,185,215
With that explanation out of the way, let's continue. Next, we take the number 271,185,215 and divide it by 2:
271,185,215 ÷ 2 = 135,592,607.5
If the quotient is a whole number, then 2 and 135,592,607.5 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 | 271,185,215 | |
| -1 | -271,185,215 |
Now, we try dividing 271,185,215 by 3:
271,185,215 ÷ 3 = 90,395,071.6667
If the quotient is a whole number, then 3 and 90,395,071.6667 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 | 271,185,215 | |
| -1 | -271,185,215 |
Let's try dividing by 4:
271,185,215 ÷ 4 = 67,796,303.75
If the quotient is a whole number, then 4 and 67,796,303.75 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 | 271,185,215 | |
| -1 | 271,185,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 149 | 349 | 745 | 1,043 | 1,745 | 2,443 | 5,215 | 12,215 | 22,201 | 52,001 | 111,005 | 155,407 | 260,005 | 364,007 | 777,035 | 1,820,035 | 7,748,149 | 38,740,745 | 54,237,043 | 271,185,215 |
| -1 | -5 | -7 | -35 | -149 | -349 | -745 | -1,043 | -1,745 | -2,443 | -5,215 | -12,215 | -22,201 | -52,001 | -111,005 | -155,407 | -260,005 | -364,007 | -777,035 | -1,820,035 | -7,748,149 | -38,740,745 | -54,237,043 | -271,185,215 |
