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 272,801,113, 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 | 272,801,113 | |
| -1 | -272,801,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 272,801,113.
Example:
1 x 272,801,113 = 272,801,113
and
-1 x -272,801,113 = 272,801,113
Notice both answers equal 272,801,113
With that explanation out of the way, let's continue. Next, we take the number 272,801,113 and divide it by 2:
272,801,113 ÷ 2 = 136,400,556.5
If the quotient is a whole number, then 2 and 136,400,556.5 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 | 272,801,113 | |
| -1 | -272,801,113 |
Now, we try dividing 272,801,113 by 3:
272,801,113 ÷ 3 = 90,933,704.3333
If the quotient is a whole number, then 3 and 90,933,704.3333 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 | 272,801,113 | |
| -1 | -272,801,113 |
Let's try dividing by 4:
272,801,113 ÷ 4 = 68,200,278.25
If the quotient is a whole number, then 4 and 68,200,278.25 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 | 272,801,113 | |
| -1 | 272,801,113 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 137 | 611 | 1,781 | 3,259 | 6,439 | 42,367 | 83,707 | 153,173 | 446,483 | 1,991,249 | 5,804,279 | 20,984,701 | 272,801,113 |
| -1 | -13 | -47 | -137 | -611 | -1,781 | -3,259 | -6,439 | -42,367 | -83,707 | -153,173 | -446,483 | -1,991,249 | -5,804,279 | -20,984,701 | -272,801,113 |
