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 18,431,315, 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 | 18,431,315 | |
| -1 | -18,431,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,431,315.
Example:
1 x 18,431,315 = 18,431,315
and
-1 x -18,431,315 = 18,431,315
Notice both answers equal 18,431,315
With that explanation out of the way, let's continue. Next, we take the number 18,431,315 and divide it by 2:
18,431,315 ÷ 2 = 9,215,657.5
If the quotient is a whole number, then 2 and 9,215,657.5 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 | 18,431,315 | |
| -1 | -18,431,315 |
Now, we try dividing 18,431,315 by 3:
18,431,315 ÷ 3 = 6,143,771.6667
If the quotient is a whole number, then 3 and 6,143,771.6667 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 | 18,431,315 | |
| -1 | -18,431,315 |
Let's try dividing by 4:
18,431,315 ÷ 4 = 4,607,828.75
If the quotient is a whole number, then 4 and 4,607,828.75 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 | 18,431,315 | |
| -1 | 18,431,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 30,977 | 154,885 | 216,839 | 526,609 | 1,084,195 | 2,633,045 | 3,686,263 | 18,431,315 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -30,977 | -154,885 | -216,839 | -526,609 | -1,084,195 | -2,633,045 | -3,686,263 | -18,431,315 |
