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 26,936,305, 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 | 26,936,305 | |
| -1 | -26,936,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,936,305.
Example:
1 x 26,936,305 = 26,936,305
and
-1 x -26,936,305 = 26,936,305
Notice both answers equal 26,936,305
With that explanation out of the way, let's continue. Next, we take the number 26,936,305 and divide it by 2:
26,936,305 ÷ 2 = 13,468,152.5
If the quotient is a whole number, then 2 and 13,468,152.5 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 | 26,936,305 | |
| -1 | -26,936,305 |
Now, we try dividing 26,936,305 by 3:
26,936,305 ÷ 3 = 8,978,768.3333
If the quotient is a whole number, then 3 and 8,978,768.3333 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 | 26,936,305 | |
| -1 | -26,936,305 |
Let's try dividing by 4:
26,936,305 ÷ 4 = 6,734,076.25
If the quotient is a whole number, then 4 and 6,734,076.25 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 | 26,936,305 | |
| -1 | 26,936,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 389 | 1,259 | 1,945 | 4,279 | 6,295 | 13,849 | 21,395 | 69,245 | 489,751 | 2,448,755 | 5,387,261 | 26,936,305 |
| -1 | -5 | -11 | -55 | -389 | -1,259 | -1,945 | -4,279 | -6,295 | -13,849 | -21,395 | -69,245 | -489,751 | -2,448,755 | -5,387,261 | -26,936,305 |
