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 1,983,949, 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 | 1,983,949 | |
| -1 | -1,983,949 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,983,949.
Example:
1 x 1,983,949 = 1,983,949
and
-1 x -1,983,949 = 1,983,949
Notice both answers equal 1,983,949
With that explanation out of the way, let's continue. Next, we take the number 1,983,949 and divide it by 2:
1,983,949 ÷ 2 = 991,974.5
If the quotient is a whole number, then 2 and 991,974.5 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 | 1,983,949 | |
| -1 | -1,983,949 |
Now, we try dividing 1,983,949 by 3:
1,983,949 ÷ 3 = 661,316.3333
If the quotient is a whole number, then 3 and 661,316.3333 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 | 1,983,949 | |
| -1 | -1,983,949 |
Let's try dividing by 4:
1,983,949 ÷ 4 = 495,987.25
If the quotient is a whole number, then 4 and 495,987.25 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 | 1,983,949 | |
| -1 | 1,983,949 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 53 | 83 | 451 | 583 | 913 | 2,173 | 3,403 | 4,399 | 23,903 | 37,433 | 48,389 | 180,359 | 1,983,949 |
| -1 | -11 | -41 | -53 | -83 | -451 | -583 | -913 | -2,173 | -3,403 | -4,399 | -23,903 | -37,433 | -48,389 | -180,359 | -1,983,949 |
