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 1,681,855, 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 | 1,681,855 | |
| -1 | -1,681,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,681,855.
Example:
1 x 1,681,855 = 1,681,855
and
-1 x -1,681,855 = 1,681,855
Notice both answers equal 1,681,855
With that explanation out of the way, let's continue. Next, we take the number 1,681,855 and divide it by 2:
1,681,855 ÷ 2 = 840,927.5
If the quotient is a whole number, then 2 and 840,927.5 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 | 1,681,855 | |
| -1 | -1,681,855 |
Now, we try dividing 1,681,855 by 3:
1,681,855 ÷ 3 = 560,618.3333
If the quotient is a whole number, then 3 and 560,618.3333 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 | 1,681,855 | |
| -1 | -1,681,855 |
Let's try dividing by 4:
1,681,855 ÷ 4 = 420,463.75
If the quotient is a whole number, then 4 and 420,463.75 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 | 1,681,855 | |
| -1 | 1,681,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 1,657 | 8,285 | 11,599 | 48,053 | 57,995 | 240,265 | 336,371 | 1,681,855 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -1,657 | -8,285 | -11,599 | -48,053 | -57,995 | -240,265 | -336,371 | -1,681,855 |
