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 18,266,375, 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 | 18,266,375 | |
| -1 | -18,266,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,266,375.
Example:
1 x 18,266,375 = 18,266,375
and
-1 x -18,266,375 = 18,266,375
Notice both answers equal 18,266,375
With that explanation out of the way, let's continue. Next, we take the number 18,266,375 and divide it by 2:
18,266,375 ÷ 2 = 9,133,187.5
If the quotient is a whole number, then 2 and 9,133,187.5 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 | 18,266,375 | |
| -1 | -18,266,375 |
Now, we try dividing 18,266,375 by 3:
18,266,375 ÷ 3 = 6,088,791.6667
If the quotient is a whole number, then 3 and 6,088,791.6667 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 | 18,266,375 | |
| -1 | -18,266,375 |
Let's try dividing by 4:
18,266,375 ÷ 4 = 4,566,593.75
If the quotient is a whole number, then 4 and 4,566,593.75 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 | 18,266,375 | |
| -1 | 18,266,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 125 | 145 | 725 | 3,625 | 5,039 | 25,195 | 125,975 | 146,131 | 629,875 | 730,655 | 3,653,275 | 18,266,375 |
| -1 | -5 | -25 | -29 | -125 | -145 | -725 | -3,625 | -5,039 | -25,195 | -125,975 | -146,131 | -629,875 | -730,655 | -3,653,275 | -18,266,375 |
