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 1,814,785, 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 | 1,814,785 | |
| -1 | -1,814,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,814,785.
Example:
1 x 1,814,785 = 1,814,785
and
-1 x -1,814,785 = 1,814,785
Notice both answers equal 1,814,785
With that explanation out of the way, let's continue. Next, we take the number 1,814,785 and divide it by 2:
1,814,785 ÷ 2 = 907,392.5
If the quotient is a whole number, then 2 and 907,392.5 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 | 1,814,785 | |
| -1 | -1,814,785 |
Now, we try dividing 1,814,785 by 3:
1,814,785 ÷ 3 = 604,928.3333
If the quotient is a whole number, then 3 and 604,928.3333 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 | 1,814,785 | |
| -1 | -1,814,785 |
Let's try dividing by 4:
1,814,785 ÷ 4 = 453,696.25
If the quotient is a whole number, then 4 and 453,696.25 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 | 1,814,785 | |
| -1 | 1,814,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 2,729 | 13,645 | 19,103 | 51,851 | 95,515 | 259,255 | 362,957 | 1,814,785 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -2,729 | -13,645 | -19,103 | -51,851 | -95,515 | -259,255 | -362,957 | -1,814,785 |
