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 1,796,665, 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 | 1,796,665 | |
| -1 | -1,796,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,796,665.
Example:
1 x 1,796,665 = 1,796,665
and
-1 x -1,796,665 = 1,796,665
Notice both answers equal 1,796,665
With that explanation out of the way, let's continue. Next, we take the number 1,796,665 and divide it by 2:
1,796,665 ÷ 2 = 898,332.5
If the quotient is a whole number, then 2 and 898,332.5 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 | 1,796,665 | |
| -1 | -1,796,665 |
Now, we try dividing 1,796,665 by 3:
1,796,665 ÷ 3 = 598,888.3333
If the quotient is a whole number, then 3 and 598,888.3333 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 | 1,796,665 | |
| -1 | -1,796,665 |
Let's try dividing by 4:
1,796,665 ÷ 4 = 449,166.25
If the quotient is a whole number, then 4 and 449,166.25 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 | 1,796,665 | |
| -1 | 1,796,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 131 | 211 | 655 | 1,055 | 1,703 | 2,743 | 8,515 | 13,715 | 27,641 | 138,205 | 359,333 | 1,796,665 |
| -1 | -5 | -13 | -65 | -131 | -211 | -655 | -1,055 | -1,703 | -2,743 | -8,515 | -13,715 | -27,641 | -138,205 | -359,333 | -1,796,665 |
