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 26,009,335, 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 | 26,009,335 | |
| -1 | -26,009,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,009,335.
Example:
1 x 26,009,335 = 26,009,335
and
-1 x -26,009,335 = 26,009,335
Notice both answers equal 26,009,335
With that explanation out of the way, let's continue. Next, we take the number 26,009,335 and divide it by 2:
26,009,335 ÷ 2 = 13,004,667.5
If the quotient is a whole number, then 2 and 13,004,667.5 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 | 26,009,335 | |
| -1 | -26,009,335 |
Now, we try dividing 26,009,335 by 3:
26,009,335 ÷ 3 = 8,669,778.3333
If the quotient is a whole number, then 3 and 8,669,778.3333 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 | 26,009,335 | |
| -1 | -26,009,335 |
Let's try dividing by 4:
26,009,335 ÷ 4 = 6,502,333.75
If the quotient is a whole number, then 4 and 6,502,333.75 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 | 26,009,335 | |
| -1 | 26,009,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 37 | 55 | 185 | 407 | 2,035 | 12,781 | 63,905 | 140,591 | 472,897 | 702,955 | 2,364,485 | 5,201,867 | 26,009,335 |
| -1 | -5 | -11 | -37 | -55 | -185 | -407 | -2,035 | -12,781 | -63,905 | -140,591 | -472,897 | -702,955 | -2,364,485 | -5,201,867 | -26,009,335 |
