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 3,310,285, 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 | 3,310,285 | |
| -1 | -3,310,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,310,285.
Example:
1 x 3,310,285 = 3,310,285
and
-1 x -3,310,285 = 3,310,285
Notice both answers equal 3,310,285
With that explanation out of the way, let's continue. Next, we take the number 3,310,285 and divide it by 2:
3,310,285 ÷ 2 = 1,655,142.5
If the quotient is a whole number, then 2 and 1,655,142.5 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 | 3,310,285 | |
| -1 | -3,310,285 |
Now, we try dividing 3,310,285 by 3:
3,310,285 ÷ 3 = 1,103,428.3333
If the quotient is a whole number, then 3 and 1,103,428.3333 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 | 3,310,285 | |
| -1 | -3,310,285 |
Let's try dividing by 4:
3,310,285 ÷ 4 = 827,571.25
If the quotient is a whole number, then 4 and 827,571.25 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 | 3,310,285 | |
| -1 | 3,310,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 139 | 433 | 695 | 1,529 | 2,165 | 4,763 | 7,645 | 23,815 | 60,187 | 300,935 | 662,057 | 3,310,285 |
| -1 | -5 | -11 | -55 | -139 | -433 | -695 | -1,529 | -2,165 | -4,763 | -7,645 | -23,815 | -60,187 | -300,935 | -662,057 | -3,310,285 |
