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 6,541,031, 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 | 6,541,031 | |
| -1 | -6,541,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,541,031.
Example:
1 x 6,541,031 = 6,541,031
and
-1 x -6,541,031 = 6,541,031
Notice both answers equal 6,541,031
With that explanation out of the way, let's continue. Next, we take the number 6,541,031 and divide it by 2:
6,541,031 ÷ 2 = 3,270,515.5
If the quotient is a whole number, then 2 and 3,270,515.5 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 | 6,541,031 | |
| -1 | -6,541,031 |
Now, we try dividing 6,541,031 by 3:
6,541,031 ÷ 3 = 2,180,343.6667
If the quotient is a whole number, then 3 and 2,180,343.6667 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 | 6,541,031 | |
| -1 | -6,541,031 |
Let's try dividing by 4:
6,541,031 ÷ 4 = 1,635,257.75
If the quotient is a whole number, then 4 and 1,635,257.75 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 | 6,541,031 | |
| -1 | 6,541,031 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 43 | 217 | 301 | 701 | 1,333 | 4,907 | 9,331 | 21,731 | 30,143 | 152,117 | 211,001 | 934,433 | 6,541,031 |
| -1 | -7 | -31 | -43 | -217 | -301 | -701 | -1,333 | -4,907 | -9,331 | -21,731 | -30,143 | -152,117 | -211,001 | -934,433 | -6,541,031 |
