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 3,122,707, 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 | 3,122,707 | |
| -1 | -3,122,707 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,122,707.
Example:
1 x 3,122,707 = 3,122,707
and
-1 x -3,122,707 = 3,122,707
Notice both answers equal 3,122,707
With that explanation out of the way, let's continue. Next, we take the number 3,122,707 and divide it by 2:
3,122,707 ÷ 2 = 1,561,353.5
If the quotient is a whole number, then 2 and 1,561,353.5 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 | 3,122,707 | |
| -1 | -3,122,707 |
Now, we try dividing 3,122,707 by 3:
3,122,707 ÷ 3 = 1,040,902.3333
If the quotient is a whole number, then 3 and 1,040,902.3333 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 | 3,122,707 | |
| -1 | -3,122,707 |
Let's try dividing by 4:
3,122,707 ÷ 4 = 780,676.75
If the quotient is a whole number, then 4 and 780,676.75 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 | 3,122,707 | |
| -1 | 3,122,707 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 53 | 133 | 371 | 443 | 1,007 | 3,101 | 7,049 | 8,417 | 23,479 | 58,919 | 164,353 | 446,101 | 3,122,707 |
| -1 | -7 | -19 | -53 | -133 | -371 | -443 | -1,007 | -3,101 | -7,049 | -8,417 | -23,479 | -58,919 | -164,353 | -446,101 | -3,122,707 |
