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 273,118,331, 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 | 273,118,331 | |
| -1 | -273,118,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 273,118,331.
Example:
1 x 273,118,331 = 273,118,331
and
-1 x -273,118,331 = 273,118,331
Notice both answers equal 273,118,331
With that explanation out of the way, let's continue. Next, we take the number 273,118,331 and divide it by 2:
273,118,331 ÷ 2 = 136,559,165.5
If the quotient is a whole number, then 2 and 136,559,165.5 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 | 273,118,331 | |
| -1 | -273,118,331 |
Now, we try dividing 273,118,331 by 3:
273,118,331 ÷ 3 = 91,039,443.6667
If the quotient is a whole number, then 3 and 91,039,443.6667 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 | 273,118,331 | |
| -1 | -273,118,331 |
Let's try dividing by 4:
273,118,331 ÷ 4 = 68,279,582.75
If the quotient is a whole number, then 4 and 68,279,582.75 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 | 273,118,331 | |
| -1 | 273,118,331 |
If you did it right, you will end up with this table:
| 1 | 19 | 67 | 73 | 1,273 | 1,387 | 2,939 | 4,891 | 55,841 | 92,929 | 196,913 | 214,547 | 3,741,347 | 4,076,393 | 14,374,649 | 273,118,331 |
| -1 | -19 | -67 | -73 | -1,273 | -1,387 | -2,939 | -4,891 | -55,841 | -92,929 | -196,913 | -214,547 | -3,741,347 | -4,076,393 | -14,374,649 | -273,118,331 |
