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 26,388,233, 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 | 26,388,233 | |
| -1 | -26,388,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 26,388,233.
Example:
1 x 26,388,233 = 26,388,233
and
-1 x -26,388,233 = 26,388,233
Notice both answers equal 26,388,233
With that explanation out of the way, let's continue. Next, we take the number 26,388,233 and divide it by 2:
26,388,233 ÷ 2 = 13,194,116.5
If the quotient is a whole number, then 2 and 13,194,116.5 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 | 26,388,233 | |
| -1 | -26,388,233 |
Now, we try dividing 26,388,233 by 3:
26,388,233 ÷ 3 = 8,796,077.6667
If the quotient is a whole number, then 3 and 8,796,077.6667 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 | 26,388,233 | |
| -1 | -26,388,233 |
Let's try dividing by 4:
26,388,233 ÷ 4 = 6,597,058.25
If the quotient is a whole number, then 4 and 6,597,058.25 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 | 26,388,233 | |
| -1 | 26,388,233 |
If you did it right, you will end up with this table:
| 1 | 17 | 89 | 107 | 163 | 1,513 | 1,819 | 2,771 | 9,523 | 14,507 | 17,441 | 161,891 | 246,619 | 296,497 | 1,552,249 | 26,388,233 |
| -1 | -17 | -89 | -107 | -163 | -1,513 | -1,819 | -2,771 | -9,523 | -14,507 | -17,441 | -161,891 | -246,619 | -296,497 | -1,552,249 | -26,388,233 |
