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 273,227,705, 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 | 273,227,705 | |
| -1 | -273,227,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,227,705.
Example:
1 x 273,227,705 = 273,227,705
and
-1 x -273,227,705 = 273,227,705
Notice both answers equal 273,227,705
With that explanation out of the way, let's continue. Next, we take the number 273,227,705 and divide it by 2:
273,227,705 ÷ 2 = 136,613,852.5
If the quotient is a whole number, then 2 and 136,613,852.5 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 | 273,227,705 | |
| -1 | -273,227,705 |
Now, we try dividing 273,227,705 by 3:
273,227,705 ÷ 3 = 91,075,901.6667
If the quotient is a whole number, then 3 and 91,075,901.6667 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 | 273,227,705 | |
| -1 | -273,227,705 |
Let's try dividing by 4:
273,227,705 ÷ 4 = 68,306,926.25
If the quotient is a whole number, then 4 and 68,306,926.25 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 | 273,227,705 | |
| -1 | 273,227,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 151 | 755 | 4,379 | 12,479 | 21,895 | 62,395 | 361,891 | 1,809,455 | 1,884,329 | 9,421,645 | 54,645,541 | 273,227,705 |
| -1 | -5 | -29 | -145 | -151 | -755 | -4,379 | -12,479 | -21,895 | -62,395 | -361,891 | -1,809,455 | -1,884,329 | -9,421,645 | -54,645,541 | -273,227,705 |
