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 273,111,443, 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 | 273,111,443 | |
| -1 | -273,111,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,111,443.
Example:
1 x 273,111,443 = 273,111,443
and
-1 x -273,111,443 = 273,111,443
Notice both answers equal 273,111,443
With that explanation out of the way, let's continue. Next, we take the number 273,111,443 and divide it by 2:
273,111,443 ÷ 2 = 136,555,721.5
If the quotient is a whole number, then 2 and 136,555,721.5 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 | 273,111,443 | |
| -1 | -273,111,443 |
Now, we try dividing 273,111,443 by 3:
273,111,443 ÷ 3 = 91,037,147.6667
If the quotient is a whole number, then 3 and 91,037,147.6667 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 | 273,111,443 | |
| -1 | -273,111,443 |
Let's try dividing by 4:
273,111,443 ÷ 4 = 68,277,860.75
If the quotient is a whole number, then 4 and 68,277,860.75 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 | 273,111,443 | |
| -1 | 273,111,443 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 181 | 187 | 1,991 | 3,077 | 8,069 | 33,847 | 88,759 | 137,173 | 1,460,489 | 1,508,903 | 16,065,379 | 24,828,313 | 273,111,443 |
| -1 | -11 | -17 | -181 | -187 | -1,991 | -3,077 | -8,069 | -33,847 | -88,759 | -137,173 | -1,460,489 | -1,508,903 | -16,065,379 | -24,828,313 | -273,111,443 |
