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 3,922,949, 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 | 3,922,949 | |
| -1 | -3,922,949 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,922,949.
Example:
1 x 3,922,949 = 3,922,949
and
-1 x -3,922,949 = 3,922,949
Notice both answers equal 3,922,949
With that explanation out of the way, let's continue. Next, we take the number 3,922,949 and divide it by 2:
3,922,949 ÷ 2 = 1,961,474.5
If the quotient is a whole number, then 2 and 1,961,474.5 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 | 3,922,949 | |
| -1 | -3,922,949 |
Now, we try dividing 3,922,949 by 3:
3,922,949 ÷ 3 = 1,307,649.6667
If the quotient is a whole number, then 3 and 1,307,649.6667 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 | 3,922,949 | |
| -1 | -3,922,949 |
Let's try dividing by 4:
3,922,949 ÷ 4 = 980,737.25
If the quotient is a whole number, then 4 and 980,737.25 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 | 3,922,949 | |
| -1 | 3,922,949 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 47 | 191 | 437 | 893 | 1,081 | 3,629 | 4,393 | 8,977 | 20,539 | 83,467 | 170,563 | 206,471 | 3,922,949 |
| -1 | -19 | -23 | -47 | -191 | -437 | -893 | -1,081 | -3,629 | -4,393 | -8,977 | -20,539 | -83,467 | -170,563 | -206,471 | -3,922,949 |
