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 26,901,835, 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 | 26,901,835 | |
| -1 | -26,901,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,901,835.
Example:
1 x 26,901,835 = 26,901,835
and
-1 x -26,901,835 = 26,901,835
Notice both answers equal 26,901,835
With that explanation out of the way, let's continue. Next, we take the number 26,901,835 and divide it by 2:
26,901,835 ÷ 2 = 13,450,917.5
If the quotient is a whole number, then 2 and 13,450,917.5 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 | 26,901,835 | |
| -1 | -26,901,835 |
Now, we try dividing 26,901,835 by 3:
26,901,835 ÷ 3 = 8,967,278.3333
If the quotient is a whole number, then 3 and 8,967,278.3333 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 | 26,901,835 | |
| -1 | -26,901,835 |
Let's try dividing by 4:
26,901,835 ÷ 4 = 6,725,458.75
If the quotient is a whole number, then 4 and 6,725,458.75 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 | 26,901,835 | |
| -1 | 26,901,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 449 | 521 | 2,245 | 2,605 | 10,327 | 11,983 | 51,635 | 59,915 | 233,929 | 1,169,645 | 5,380,367 | 26,901,835 |
| -1 | -5 | -23 | -115 | -449 | -521 | -2,245 | -2,605 | -10,327 | -11,983 | -51,635 | -59,915 | -233,929 | -1,169,645 | -5,380,367 | -26,901,835 |
