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 26,011,835, 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 | 26,011,835 | |
| -1 | -26,011,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,011,835.
Example:
1 x 26,011,835 = 26,011,835
and
-1 x -26,011,835 = 26,011,835
Notice both answers equal 26,011,835
With that explanation out of the way, let's continue. Next, we take the number 26,011,835 and divide it by 2:
26,011,835 ÷ 2 = 13,005,917.5
If the quotient is a whole number, then 2 and 13,005,917.5 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 | 26,011,835 | |
| -1 | -26,011,835 |
Now, we try dividing 26,011,835 by 3:
26,011,835 ÷ 3 = 8,670,611.6667
If the quotient is a whole number, then 3 and 8,670,611.6667 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 | 26,011,835 | |
| -1 | -26,011,835 |
Let's try dividing by 4:
26,011,835 ÷ 4 = 6,502,958.75
If the quotient is a whole number, then 4 and 6,502,958.75 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 | 26,011,835 | |
| -1 | 26,011,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 223 | 569 | 1,115 | 2,845 | 9,143 | 23,329 | 45,715 | 116,645 | 126,887 | 634,435 | 5,202,367 | 26,011,835 |
| -1 | -5 | -41 | -205 | -223 | -569 | -1,115 | -2,845 | -9,143 | -23,329 | -45,715 | -116,645 | -126,887 | -634,435 | -5,202,367 | -26,011,835 |
