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 18,237,005, 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 | 18,237,005 | |
| -1 | -18,237,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,237,005.
Example:
1 x 18,237,005 = 18,237,005
and
-1 x -18,237,005 = 18,237,005
Notice both answers equal 18,237,005
With that explanation out of the way, let's continue. Next, we take the number 18,237,005 and divide it by 2:
18,237,005 ÷ 2 = 9,118,502.5
If the quotient is a whole number, then 2 and 9,118,502.5 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 | 18,237,005 | |
| -1 | -18,237,005 |
Now, we try dividing 18,237,005 by 3:
18,237,005 ÷ 3 = 6,079,001.6667
If the quotient is a whole number, then 3 and 6,079,001.6667 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 | 18,237,005 | |
| -1 | -18,237,005 |
Let's try dividing by 4:
18,237,005 ÷ 4 = 4,559,251.25
If the quotient is a whole number, then 4 and 4,559,251.25 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 | 18,237,005 | |
| -1 | 18,237,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 41 | 85 | 205 | 697 | 3,485 | 5,233 | 26,165 | 88,961 | 214,553 | 444,805 | 1,072,765 | 3,647,401 | 18,237,005 |
| -1 | -5 | -17 | -41 | -85 | -205 | -697 | -3,485 | -5,233 | -26,165 | -88,961 | -214,553 | -444,805 | -1,072,765 | -3,647,401 | -18,237,005 |
