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 26,305,055, 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 | 26,305,055 | |
| -1 | -26,305,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,305,055.
Example:
1 x 26,305,055 = 26,305,055
and
-1 x -26,305,055 = 26,305,055
Notice both answers equal 26,305,055
With that explanation out of the way, let's continue. Next, we take the number 26,305,055 and divide it by 2:
26,305,055 ÷ 2 = 13,152,527.5
If the quotient is a whole number, then 2 and 13,152,527.5 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 | 26,305,055 | |
| -1 | -26,305,055 |
Now, we try dividing 26,305,055 by 3:
26,305,055 ÷ 3 = 8,768,351.6667
If the quotient is a whole number, then 3 and 8,768,351.6667 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 | 26,305,055 | |
| -1 | -26,305,055 |
Let's try dividing by 4:
26,305,055 ÷ 4 = 6,576,263.75
If the quotient is a whole number, then 4 and 6,576,263.75 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 | 26,305,055 | |
| -1 | 26,305,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 139 | 695 | 973 | 4,865 | 5,407 | 27,035 | 37,849 | 189,245 | 751,573 | 3,757,865 | 5,261,011 | 26,305,055 |
| -1 | -5 | -7 | -35 | -139 | -695 | -973 | -4,865 | -5,407 | -27,035 | -37,849 | -189,245 | -751,573 | -3,757,865 | -5,261,011 | -26,305,055 |
