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 1,818,845, 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 | 1,818,845 | |
| -1 | -1,818,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,818,845.
Example:
1 x 1,818,845 = 1,818,845
and
-1 x -1,818,845 = 1,818,845
Notice both answers equal 1,818,845
With that explanation out of the way, let's continue. Next, we take the number 1,818,845 and divide it by 2:
1,818,845 ÷ 2 = 909,422.5
If the quotient is a whole number, then 2 and 909,422.5 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 | 1,818,845 | |
| -1 | -1,818,845 |
Now, we try dividing 1,818,845 by 3:
1,818,845 ÷ 3 = 606,281.6667
If the quotient is a whole number, then 3 and 606,281.6667 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 | 1,818,845 | |
| -1 | -1,818,845 |
Let's try dividing by 4:
1,818,845 ÷ 4 = 454,711.25
If the quotient is a whole number, then 4 and 454,711.25 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 | 1,818,845 | |
| -1 | 1,818,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 157 | 331 | 785 | 1,099 | 1,655 | 2,317 | 5,495 | 11,585 | 51,967 | 259,835 | 363,769 | 1,818,845 |
| -1 | -5 | -7 | -35 | -157 | -331 | -785 | -1,099 | -1,655 | -2,317 | -5,495 | -11,585 | -51,967 | -259,835 | -363,769 | -1,818,845 |
