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 26,005,801, 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 | 26,005,801 | |
| -1 | -26,005,801 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,005,801.
Example:
1 x 26,005,801 = 26,005,801
and
-1 x -26,005,801 = 26,005,801
Notice both answers equal 26,005,801
With that explanation out of the way, let's continue. Next, we take the number 26,005,801 and divide it by 2:
26,005,801 ÷ 2 = 13,002,900.5
If the quotient is a whole number, then 2 and 13,002,900.5 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 | 26,005,801 | |
| -1 | -26,005,801 |
Now, we try dividing 26,005,801 by 3:
26,005,801 ÷ 3 = 8,668,600.3333
If the quotient is a whole number, then 3 and 8,668,600.3333 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 | 26,005,801 | |
| -1 | -26,005,801 |
Let's try dividing by 4:
26,005,801 ÷ 4 = 6,501,450.25
If the quotient is a whole number, then 4 and 6,501,450.25 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 | 26,005,801 | |
| -1 | 26,005,801 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 227 | 293 | 391 | 3,859 | 4,981 | 5,221 | 6,739 | 66,511 | 88,757 | 114,563 | 1,130,687 | 1,529,753 | 26,005,801 |
| -1 | -17 | -23 | -227 | -293 | -391 | -3,859 | -4,981 | -5,221 | -6,739 | -66,511 | -88,757 | -114,563 | -1,130,687 | -1,529,753 | -26,005,801 |
