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 3,809,215, 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 | 3,809,215 | |
| -1 | -3,809,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,809,215.
Example:
1 x 3,809,215 = 3,809,215
and
-1 x -3,809,215 = 3,809,215
Notice both answers equal 3,809,215
With that explanation out of the way, let's continue. Next, we take the number 3,809,215 and divide it by 2:
3,809,215 ÷ 2 = 1,904,607.5
If the quotient is a whole number, then 2 and 1,904,607.5 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 | 3,809,215 | |
| -1 | -3,809,215 |
Now, we try dividing 3,809,215 by 3:
3,809,215 ÷ 3 = 1,269,738.3333
If the quotient is a whole number, then 3 and 1,269,738.3333 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 | 3,809,215 | |
| -1 | -3,809,215 |
Let's try dividing by 4:
3,809,215 ÷ 4 = 952,303.75
If the quotient is a whole number, then 4 and 952,303.75 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 | 3,809,215 | |
| -1 | 3,809,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 101 | 397 | 505 | 1,919 | 1,985 | 7,543 | 9,595 | 37,715 | 40,097 | 200,485 | 761,843 | 3,809,215 |
| -1 | -5 | -19 | -95 | -101 | -397 | -505 | -1,919 | -1,985 | -7,543 | -9,595 | -37,715 | -40,097 | -200,485 | -761,843 | -3,809,215 |
