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 3,270,839, 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 | 3,270,839 | |
| -1 | -3,270,839 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,270,839.
Example:
1 x 3,270,839 = 3,270,839
and
-1 x -3,270,839 = 3,270,839
Notice both answers equal 3,270,839
With that explanation out of the way, let's continue. Next, we take the number 3,270,839 and divide it by 2:
3,270,839 ÷ 2 = 1,635,419.5
If the quotient is a whole number, then 2 and 1,635,419.5 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 | 3,270,839 | |
| -1 | -3,270,839 |
Now, we try dividing 3,270,839 by 3:
3,270,839 ÷ 3 = 1,090,279.6667
If the quotient is a whole number, then 3 and 1,090,279.6667 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 | 3,270,839 | |
| -1 | -3,270,839 |
Let's try dividing by 4:
3,270,839 ÷ 4 = 817,709.75
If the quotient is a whole number, then 4 and 817,709.75 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 | 3,270,839 | |
| -1 | 3,270,839 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 89 | 143 | 257 | 979 | 1,157 | 2,827 | 3,341 | 12,727 | 22,873 | 36,751 | 251,603 | 297,349 | 3,270,839 |
| -1 | -11 | -13 | -89 | -143 | -257 | -979 | -1,157 | -2,827 | -3,341 | -12,727 | -22,873 | -36,751 | -251,603 | -297,349 | -3,270,839 |
