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 273,223,831, 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 | 273,223,831 | |
| -1 | -273,223,831 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,223,831.
Example:
1 x 273,223,831 = 273,223,831
and
-1 x -273,223,831 = 273,223,831
Notice both answers equal 273,223,831
With that explanation out of the way, let's continue. Next, we take the number 273,223,831 and divide it by 2:
273,223,831 ÷ 2 = 136,611,915.5
If the quotient is a whole number, then 2 and 136,611,915.5 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 | 273,223,831 | |
| -1 | -273,223,831 |
Now, we try dividing 273,223,831 by 3:
273,223,831 ÷ 3 = 91,074,610.3333
If the quotient is a whole number, then 3 and 91,074,610.3333 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 | 273,223,831 | |
| -1 | -273,223,831 |
Let's try dividing by 4:
273,223,831 ÷ 4 = 68,305,957.75
If the quotient is a whole number, then 4 and 68,305,957.75 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 | 273,223,831 | |
| -1 | 273,223,831 |
If you did it right, you will end up with this table:
| 1 | 23 | 47 | 197 | 1,081 | 1,283 | 4,531 | 9,259 | 29,509 | 60,301 | 212,957 | 252,751 | 1,386,923 | 5,813,273 | 11,879,297 | 273,223,831 |
| -1 | -23 | -47 | -197 | -1,081 | -1,283 | -4,531 | -9,259 | -29,509 | -60,301 | -212,957 | -252,751 | -1,386,923 | -5,813,273 | -11,879,297 | -273,223,831 |
