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 18,359,605, 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 | 18,359,605 | |
| -1 | -18,359,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,359,605.
Example:
1 x 18,359,605 = 18,359,605
and
-1 x -18,359,605 = 18,359,605
Notice both answers equal 18,359,605
With that explanation out of the way, let's continue. Next, we take the number 18,359,605 and divide it by 2:
18,359,605 ÷ 2 = 9,179,802.5
If the quotient is a whole number, then 2 and 9,179,802.5 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 | 18,359,605 | |
| -1 | -18,359,605 |
Now, we try dividing 18,359,605 by 3:
18,359,605 ÷ 3 = 6,119,868.3333
If the quotient is a whole number, then 3 and 6,119,868.3333 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 | 18,359,605 | |
| -1 | -18,359,605 |
Let's try dividing by 4:
18,359,605 ÷ 4 = 4,589,901.25
If the quotient is a whole number, then 4 and 4,589,901.25 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 | 18,359,605 | |
| -1 | 18,359,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 17,569 | 87,845 | 193,259 | 333,811 | 966,295 | 1,669,055 | 3,671,921 | 18,359,605 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -17,569 | -87,845 | -193,259 | -333,811 | -966,295 | -1,669,055 | -3,671,921 | -18,359,605 |
