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 3,108,743, 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 | 3,108,743 | |
| -1 | -3,108,743 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,108,743.
Example:
1 x 3,108,743 = 3,108,743
and
-1 x -3,108,743 = 3,108,743
Notice both answers equal 3,108,743
With that explanation out of the way, let's continue. Next, we take the number 3,108,743 and divide it by 2:
3,108,743 ÷ 2 = 1,554,371.5
If the quotient is a whole number, then 2 and 1,554,371.5 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 | 3,108,743 | |
| -1 | -3,108,743 |
Now, we try dividing 3,108,743 by 3:
3,108,743 ÷ 3 = 1,036,247.6667
If the quotient is a whole number, then 3 and 1,036,247.6667 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 | 3,108,743 | |
| -1 | -3,108,743 |
Let's try dividing by 4:
3,108,743 ÷ 4 = 777,185.75
If the quotient is a whole number, then 4 and 777,185.75 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 | 3,108,743 | |
| -1 | 3,108,743 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 61 | 113 | 451 | 671 | 1,243 | 2,501 | 4,633 | 6,893 | 27,511 | 50,963 | 75,823 | 282,613 | 3,108,743 |
| -1 | -11 | -41 | -61 | -113 | -451 | -671 | -1,243 | -2,501 | -4,633 | -6,893 | -27,511 | -50,963 | -75,823 | -282,613 | -3,108,743 |
