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 273,050,869, 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 | 273,050,869 | |
| -1 | -273,050,869 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,050,869.
Example:
1 x 273,050,869 = 273,050,869
and
-1 x -273,050,869 = 273,050,869
Notice both answers equal 273,050,869
With that explanation out of the way, let's continue. Next, we take the number 273,050,869 and divide it by 2:
273,050,869 ÷ 2 = 136,525,434.5
If the quotient is a whole number, then 2 and 136,525,434.5 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 | 273,050,869 | |
| -1 | -273,050,869 |
Now, we try dividing 273,050,869 by 3:
273,050,869 ÷ 3 = 91,016,956.3333
If the quotient is a whole number, then 3 and 91,016,956.3333 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 | 273,050,869 | |
| -1 | -273,050,869 |
Let's try dividing by 4:
273,050,869 ÷ 4 = 68,262,717.25
If the quotient is a whole number, then 4 and 68,262,717.25 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 | 273,050,869 | |
| -1 | 273,050,869 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 557 | 3,899 | 5,387 | 7,241 | 37,709 | 50,687 | 70,031 | 490,217 | 3,000,559 | 21,003,913 | 39,007,267 | 273,050,869 |
| -1 | -7 | -13 | -91 | -557 | -3,899 | -5,387 | -7,241 | -37,709 | -50,687 | -70,031 | -490,217 | -3,000,559 | -21,003,913 | -39,007,267 | -273,050,869 |
