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 272,004,109, 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 | 272,004,109 | |
| -1 | -272,004,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 272,004,109.
Example:
1 x 272,004,109 = 272,004,109
and
-1 x -272,004,109 = 272,004,109
Notice both answers equal 272,004,109
With that explanation out of the way, let's continue. Next, we take the number 272,004,109 and divide it by 2:
272,004,109 ÷ 2 = 136,002,054.5
If the quotient is a whole number, then 2 and 136,002,054.5 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 | 272,004,109 | |
| -1 | -272,004,109 |
Now, we try dividing 272,004,109 by 3:
272,004,109 ÷ 3 = 90,668,036.3333
If the quotient is a whole number, then 3 and 90,668,036.3333 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 | 272,004,109 | |
| -1 | -272,004,109 |
Let's try dividing by 4:
272,004,109 ÷ 4 = 68,001,027.25
If the quotient is a whole number, then 4 and 68,001,027.25 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 | 272,004,109 | |
| -1 | 272,004,109 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 211 | 689 | 1,871 | 2,743 | 11,183 | 24,323 | 99,163 | 145,379 | 394,781 | 1,289,119 | 5,132,153 | 20,923,393 | 272,004,109 |
| -1 | -13 | -53 | -211 | -689 | -1,871 | -2,743 | -11,183 | -24,323 | -99,163 | -145,379 | -394,781 | -1,289,119 | -5,132,153 | -20,923,393 | -272,004,109 |
