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 3,197,681, 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 | 3,197,681 | |
| -1 | -3,197,681 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,197,681.
Example:
1 x 3,197,681 = 3,197,681
and
-1 x -3,197,681 = 3,197,681
Notice both answers equal 3,197,681
With that explanation out of the way, let's continue. Next, we take the number 3,197,681 and divide it by 2:
3,197,681 ÷ 2 = 1,598,840.5
If the quotient is a whole number, then 2 and 1,598,840.5 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 | 3,197,681 | |
| -1 | -3,197,681 |
Now, we try dividing 3,197,681 by 3:
3,197,681 ÷ 3 = 1,065,893.6667
If the quotient is a whole number, then 3 and 1,065,893.6667 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 | 3,197,681 | |
| -1 | -3,197,681 |
Let's try dividing by 4:
3,197,681 ÷ 4 = 799,420.25
If the quotient is a whole number, then 4 and 799,420.25 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 | 3,197,681 | |
| -1 | 3,197,681 |
If you did it right, you will end up with this table:
| 1 | 19 | 31 | 61 | 89 | 589 | 1,159 | 1,691 | 1,891 | 2,759 | 5,429 | 35,929 | 52,421 | 103,151 | 168,299 | 3,197,681 |
| -1 | -19 | -31 | -61 | -89 | -589 | -1,159 | -1,691 | -1,891 | -2,759 | -5,429 | -35,929 | -52,421 | -103,151 | -168,299 | -3,197,681 |
