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 3,106,187, 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 | 3,106,187 | |
| -1 | -3,106,187 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,106,187.
Example:
1 x 3,106,187 = 3,106,187
and
-1 x -3,106,187 = 3,106,187
Notice both answers equal 3,106,187
With that explanation out of the way, let's continue. Next, we take the number 3,106,187 and divide it by 2:
3,106,187 ÷ 2 = 1,553,093.5
If the quotient is a whole number, then 2 and 1,553,093.5 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 | 3,106,187 | |
| -1 | -3,106,187 |
Now, we try dividing 3,106,187 by 3:
3,106,187 ÷ 3 = 1,035,395.6667
If the quotient is a whole number, then 3 and 1,035,395.6667 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 | 3,106,187 | |
| -1 | -3,106,187 |
Let's try dividing by 4:
3,106,187 ÷ 4 = 776,546.75
If the quotient is a whole number, then 4 and 776,546.75 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 | 3,106,187 | |
| -1 | 3,106,187 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 67 | 179 | 259 | 469 | 1,253 | 2,479 | 6,623 | 11,993 | 17,353 | 46,361 | 83,951 | 443,741 | 3,106,187 |
| -1 | -7 | -37 | -67 | -179 | -259 | -469 | -1,253 | -2,479 | -6,623 | -11,993 | -17,353 | -46,361 | -83,951 | -443,741 | -3,106,187 |
