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 3,992,263, 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 | 3,992,263 | |
| -1 | -3,992,263 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,992,263.
Example:
1 x 3,992,263 = 3,992,263
and
-1 x -3,992,263 = 3,992,263
Notice both answers equal 3,992,263
With that explanation out of the way, let's continue. Next, we take the number 3,992,263 and divide it by 2:
3,992,263 ÷ 2 = 1,996,131.5
If the quotient is a whole number, then 2 and 1,996,131.5 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 | 3,992,263 | |
| -1 | -3,992,263 |
Now, we try dividing 3,992,263 by 3:
3,992,263 ÷ 3 = 1,330,754.3333
If the quotient is a whole number, then 3 and 1,330,754.3333 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 | 3,992,263 | |
| -1 | -3,992,263 |
Let's try dividing by 4:
3,992,263 ÷ 4 = 998,065.75
If the quotient is a whole number, then 4 and 998,065.75 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 | 3,992,263 | |
| -1 | 3,992,263 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 37 | 187 | 407 | 577 | 629 | 6,347 | 6,919 | 9,809 | 21,349 | 107,899 | 234,839 | 362,933 | 3,992,263 |
| -1 | -11 | -17 | -37 | -187 | -407 | -577 | -629 | -6,347 | -6,919 | -9,809 | -21,349 | -107,899 | -234,839 | -362,933 | -3,992,263 |
