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 271,053,013, 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 | 271,053,013 | |
| -1 | -271,053,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 271,053,013.
Example:
1 x 271,053,013 = 271,053,013
and
-1 x -271,053,013 = 271,053,013
Notice both answers equal 271,053,013
With that explanation out of the way, let's continue. Next, we take the number 271,053,013 and divide it by 2:
271,053,013 ÷ 2 = 135,526,506.5
If the quotient is a whole number, then 2 and 135,526,506.5 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 | 271,053,013 | |
| -1 | -271,053,013 |
Now, we try dividing 271,053,013 by 3:
271,053,013 ÷ 3 = 90,351,004.3333
If the quotient is a whole number, then 3 and 90,351,004.3333 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 | 271,053,013 | |
| -1 | -271,053,013 |
Let's try dividing by 4:
271,053,013 ÷ 4 = 67,763,253.25
If the quotient is a whole number, then 4 and 67,763,253.25 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 | 271,053,013 | |
| -1 | 271,053,013 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 1,381 | 2,549 | 9,667 | 15,191 | 17,843 | 28,039 | 106,337 | 196,273 | 3,520,169 | 24,641,183 | 38,721,859 | 271,053,013 |
| -1 | -7 | -11 | -77 | -1,381 | -2,549 | -9,667 | -15,191 | -17,843 | -28,039 | -106,337 | -196,273 | -3,520,169 | -24,641,183 | -38,721,859 | -271,053,013 |
