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 1,818,883, 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 | 1,818,883 | |
| -1 | -1,818,883 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,818,883.
Example:
1 x 1,818,883 = 1,818,883
and
-1 x -1,818,883 = 1,818,883
Notice both answers equal 1,818,883
With that explanation out of the way, let's continue. Next, we take the number 1,818,883 and divide it by 2:
1,818,883 ÷ 2 = 909,441.5
If the quotient is a whole number, then 2 and 909,441.5 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 | 1,818,883 | |
| -1 | -1,818,883 |
Now, we try dividing 1,818,883 by 3:
1,818,883 ÷ 3 = 606,294.3333
If the quotient is a whole number, then 3 and 606,294.3333 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 | 1,818,883 | |
| -1 | -1,818,883 |
Let's try dividing by 4:
1,818,883 ÷ 4 = 454,720.75
If the quotient is a whole number, then 4 and 454,720.75 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 | 1,818,883 | |
| -1 | 1,818,883 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 41 | 109 | 407 | 451 | 1,199 | 1,517 | 4,033 | 4,469 | 16,687 | 44,363 | 49,159 | 165,353 | 1,818,883 |
| -1 | -11 | -37 | -41 | -109 | -407 | -451 | -1,199 | -1,517 | -4,033 | -4,469 | -16,687 | -44,363 | -49,159 | -165,353 | -1,818,883 |
