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 3,110,315, 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 | 3,110,315 | |
| -1 | -3,110,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,110,315.
Example:
1 x 3,110,315 = 3,110,315
and
-1 x -3,110,315 = 3,110,315
Notice both answers equal 3,110,315
With that explanation out of the way, let's continue. Next, we take the number 3,110,315 and divide it by 2:
3,110,315 ÷ 2 = 1,555,157.5
If the quotient is a whole number, then 2 and 1,555,157.5 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 | 3,110,315 | |
| -1 | -3,110,315 |
Now, we try dividing 3,110,315 by 3:
3,110,315 ÷ 3 = 1,036,771.6667
If the quotient is a whole number, then 3 and 1,036,771.6667 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 | 3,110,315 | |
| -1 | -3,110,315 |
Let's try dividing by 4:
3,110,315 ÷ 4 = 777,578.75
If the quotient is a whole number, then 4 and 777,578.75 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 | 3,110,315 | |
| -1 | 3,110,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 109 | 439 | 545 | 1,417 | 2,195 | 5,707 | 7,085 | 28,535 | 47,851 | 239,255 | 622,063 | 3,110,315 |
| -1 | -5 | -13 | -65 | -109 | -439 | -545 | -1,417 | -2,195 | -5,707 | -7,085 | -28,535 | -47,851 | -239,255 | -622,063 | -3,110,315 |
