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 3,996,635, 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 | 3,996,635 | |
| -1 | -3,996,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,996,635.
Example:
1 x 3,996,635 = 3,996,635
and
-1 x -3,996,635 = 3,996,635
Notice both answers equal 3,996,635
With that explanation out of the way, let's continue. Next, we take the number 3,996,635 and divide it by 2:
3,996,635 ÷ 2 = 1,998,317.5
If the quotient is a whole number, then 2 and 1,998,317.5 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 | 3,996,635 | |
| -1 | -3,996,635 |
Now, we try dividing 3,996,635 by 3:
3,996,635 ÷ 3 = 1,332,211.6667
If the quotient is a whole number, then 3 and 1,332,211.6667 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 | 3,996,635 | |
| -1 | -3,996,635 |
Let's try dividing by 4:
3,996,635 ÷ 4 = 999,158.75
If the quotient is a whole number, then 4 and 999,158.75 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 | 3,996,635 | |
| -1 | 3,996,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 43 | 145 | 215 | 641 | 1,247 | 3,205 | 6,235 | 18,589 | 27,563 | 92,945 | 137,815 | 799,327 | 3,996,635 |
| -1 | -5 | -29 | -43 | -145 | -215 | -641 | -1,247 | -3,205 | -6,235 | -18,589 | -27,563 | -92,945 | -137,815 | -799,327 | -3,996,635 |
