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 18,450,983, 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 | 18,450,983 | |
| -1 | -18,450,983 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,450,983.
Example:
1 x 18,450,983 = 18,450,983
and
-1 x -18,450,983 = 18,450,983
Notice both answers equal 18,450,983
With that explanation out of the way, let's continue. Next, we take the number 18,450,983 and divide it by 2:
18,450,983 ÷ 2 = 9,225,491.5
If the quotient is a whole number, then 2 and 9,225,491.5 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 | 18,450,983 | |
| -1 | -18,450,983 |
Now, we try dividing 18,450,983 by 3:
18,450,983 ÷ 3 = 6,150,327.6667
If the quotient is a whole number, then 3 and 6,150,327.6667 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 | 18,450,983 | |
| -1 | -18,450,983 |
Let's try dividing by 4:
18,450,983 ÷ 4 = 4,612,745.75
If the quotient is a whole number, then 4 and 4,612,745.75 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 | 18,450,983 | |
| -1 | 18,450,983 |
If you did it right, you will end up with this table:
| 1 | 31 | 71 | 83 | 101 | 2,201 | 2,573 | 3,131 | 5,893 | 7,171 | 8,383 | 182,683 | 222,301 | 259,873 | 595,193 | 18,450,983 |
| -1 | -31 | -71 | -83 | -101 | -2,201 | -2,573 | -3,131 | -5,893 | -7,171 | -8,383 | -182,683 | -222,301 | -259,873 | -595,193 | -18,450,983 |
