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 18,566,135, 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 | 18,566,135 | |
| -1 | -18,566,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,566,135.
Example:
1 x 18,566,135 = 18,566,135
and
-1 x -18,566,135 = 18,566,135
Notice both answers equal 18,566,135
With that explanation out of the way, let's continue. Next, we take the number 18,566,135 and divide it by 2:
18,566,135 ÷ 2 = 9,283,067.5
If the quotient is a whole number, then 2 and 9,283,067.5 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 | 18,566,135 | |
| -1 | -18,566,135 |
Now, we try dividing 18,566,135 by 3:
18,566,135 ÷ 3 = 6,188,711.6667
If the quotient is a whole number, then 3 and 6,188,711.6667 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 | 18,566,135 | |
| -1 | -18,566,135 |
Let's try dividing by 4:
18,566,135 ÷ 4 = 4,641,533.75
If the quotient is a whole number, then 4 and 4,641,533.75 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 | 18,566,135 | |
| -1 | 18,566,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 27,919 | 139,595 | 195,433 | 530,461 | 977,165 | 2,652,305 | 3,713,227 | 18,566,135 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -27,919 | -139,595 | -195,433 | -530,461 | -977,165 | -2,652,305 | -3,713,227 | -18,566,135 |
