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 271,213,873, 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 | 271,213,873 | |
| -1 | -271,213,873 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,213,873.
Example:
1 x 271,213,873 = 271,213,873
and
-1 x -271,213,873 = 271,213,873
Notice both answers equal 271,213,873
With that explanation out of the way, let's continue. Next, we take the number 271,213,873 and divide it by 2:
271,213,873 ÷ 2 = 135,606,936.5
If the quotient is a whole number, then 2 and 135,606,936.5 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 | 271,213,873 | |
| -1 | -271,213,873 |
Now, we try dividing 271,213,873 by 3:
271,213,873 ÷ 3 = 90,404,624.3333
If the quotient is a whole number, then 3 and 90,404,624.3333 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 | 271,213,873 | |
| -1 | -271,213,873 |
Let's try dividing by 4:
271,213,873 ÷ 4 = 67,803,468.25
If the quotient is a whole number, then 4 and 67,803,468.25 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 | 271,213,873 | |
| -1 | 271,213,873 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 79 | 343 | 553 | 3,871 | 10,009 | 27,097 | 70,063 | 490,441 | 790,711 | 3,433,087 | 5,534,977 | 38,744,839 | 271,213,873 |
| -1 | -7 | -49 | -79 | -343 | -553 | -3,871 | -10,009 | -27,097 | -70,063 | -490,441 | -790,711 | -3,433,087 | -5,534,977 | -38,744,839 | -271,213,873 |
