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 3,110,305, 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 | 3,110,305 | |
| -1 | -3,110,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,110,305.
Example:
1 x 3,110,305 = 3,110,305
and
-1 x -3,110,305 = 3,110,305
Notice both answers equal 3,110,305
With that explanation out of the way, let's continue. Next, we take the number 3,110,305 and divide it by 2:
3,110,305 ÷ 2 = 1,555,152.5
If the quotient is a whole number, then 2 and 1,555,152.5 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 | 3,110,305 | |
| -1 | -3,110,305 |
Now, we try dividing 3,110,305 by 3:
3,110,305 ÷ 3 = 1,036,768.3333
If the quotient is a whole number, then 3 and 1,036,768.3333 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 | 3,110,305 | |
| -1 | -3,110,305 |
Let's try dividing by 4:
3,110,305 ÷ 4 = 777,576.25
If the quotient is a whole number, then 4 and 777,576.25 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 | 3,110,305 | |
| -1 | 3,110,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 53 | 55 | 97 | 121 | 265 | 485 | 583 | 605 | 1,067 | 2,915 | 5,141 | 5,335 | 6,413 | 11,737 | 25,705 | 32,065 | 56,551 | 58,685 | 282,755 | 622,061 | 3,110,305 |
| -1 | -5 | -11 | -53 | -55 | -97 | -121 | -265 | -485 | -583 | -605 | -1,067 | -2,915 | -5,141 | -5,335 | -6,413 | -11,737 | -25,705 | -32,065 | -56,551 | -58,685 | -282,755 | -622,061 | -3,110,305 |
