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 3,101,105, 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 | 3,101,105 | |
| -1 | -3,101,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,101,105.
Example:
1 x 3,101,105 = 3,101,105
and
-1 x -3,101,105 = 3,101,105
Notice both answers equal 3,101,105
With that explanation out of the way, let's continue. Next, we take the number 3,101,105 and divide it by 2:
3,101,105 ÷ 2 = 1,550,552.5
If the quotient is a whole number, then 2 and 1,550,552.5 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 | 3,101,105 | |
| -1 | -3,101,105 |
Now, we try dividing 3,101,105 by 3:
3,101,105 ÷ 3 = 1,033,701.6667
If the quotient is a whole number, then 3 and 1,033,701.6667 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 | 3,101,105 | |
| -1 | -3,101,105 |
Let's try dividing by 4:
3,101,105 ÷ 4 = 775,276.25
If the quotient is a whole number, then 4 and 775,276.25 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 | 3,101,105 | |
| -1 | 3,101,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 251 | 353 | 1,255 | 1,757 | 1,765 | 2,471 | 8,785 | 12,355 | 88,603 | 443,015 | 620,221 | 3,101,105 |
| -1 | -5 | -7 | -35 | -251 | -353 | -1,255 | -1,757 | -1,765 | -2,471 | -8,785 | -12,355 | -88,603 | -443,015 | -620,221 | -3,101,105 |
