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 18,323,635, 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 | 18,323,635 | |
| -1 | -18,323,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,323,635.
Example:
1 x 18,323,635 = 18,323,635
and
-1 x -18,323,635 = 18,323,635
Notice both answers equal 18,323,635
With that explanation out of the way, let's continue. Next, we take the number 18,323,635 and divide it by 2:
18,323,635 ÷ 2 = 9,161,817.5
If the quotient is a whole number, then 2 and 9,161,817.5 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 | 18,323,635 | |
| -1 | -18,323,635 |
Now, we try dividing 18,323,635 by 3:
18,323,635 ÷ 3 = 6,107,878.3333
If the quotient is a whole number, then 3 and 6,107,878.3333 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 | 18,323,635 | |
| -1 | -18,323,635 |
Let's try dividing by 4:
18,323,635 ÷ 4 = 4,580,908.75
If the quotient is a whole number, then 4 and 4,580,908.75 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 | 18,323,635 | |
| -1 | 18,323,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 121 | 155 | 341 | 605 | 977 | 1,705 | 3,751 | 4,885 | 10,747 | 18,755 | 30,287 | 53,735 | 118,217 | 151,435 | 333,157 | 591,085 | 1,665,785 | 3,664,727 | 18,323,635 |
| -1 | -5 | -11 | -31 | -55 | -121 | -155 | -341 | -605 | -977 | -1,705 | -3,751 | -4,885 | -10,747 | -18,755 | -30,287 | -53,735 | -118,217 | -151,435 | -333,157 | -591,085 | -1,665,785 | -3,664,727 | -18,323,635 |
