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 3,236,885, 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 | 3,236,885 | |
| -1 | -3,236,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,236,885.
Example:
1 x 3,236,885 = 3,236,885
and
-1 x -3,236,885 = 3,236,885
Notice both answers equal 3,236,885
With that explanation out of the way, let's continue. Next, we take the number 3,236,885 and divide it by 2:
3,236,885 ÷ 2 = 1,618,442.5
If the quotient is a whole number, then 2 and 1,618,442.5 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 | 3,236,885 | |
| -1 | -3,236,885 |
Now, we try dividing 3,236,885 by 3:
3,236,885 ÷ 3 = 1,078,961.6667
If the quotient is a whole number, then 3 and 1,078,961.6667 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 | 3,236,885 | |
| -1 | -3,236,885 |
Let's try dividing by 4:
3,236,885 ÷ 4 = 809,221.25
If the quotient is a whole number, then 4 and 809,221.25 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 | 3,236,885 | |
| -1 | 3,236,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 113 | 337 | 565 | 1,685 | 1,921 | 5,729 | 9,605 | 28,645 | 38,081 | 190,405 | 647,377 | 3,236,885 |
| -1 | -5 | -17 | -85 | -113 | -337 | -565 | -1,685 | -1,921 | -5,729 | -9,605 | -28,645 | -38,081 | -190,405 | -647,377 | -3,236,885 |
