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 5,340,881, 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 | 5,340,881 | |
| -1 | -5,340,881 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,340,881.
Example:
1 x 5,340,881 = 5,340,881
and
-1 x -5,340,881 = 5,340,881
Notice both answers equal 5,340,881
With that explanation out of the way, let's continue. Next, we take the number 5,340,881 and divide it by 2:
5,340,881 ÷ 2 = 2,670,440.5
If the quotient is a whole number, then 2 and 2,670,440.5 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 | 5,340,881 | |
| -1 | -5,340,881 |
Now, we try dividing 5,340,881 by 3:
5,340,881 ÷ 3 = 1,780,293.6667
If the quotient is a whole number, then 3 and 1,780,293.6667 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 | 5,340,881 | |
| -1 | -5,340,881 |
Let's try dividing by 4:
5,340,881 ÷ 4 = 1,335,220.25
If the quotient is a whole number, then 4 and 1,335,220.25 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 | 5,340,881 | |
| -1 | 5,340,881 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 19 | 91 | 133 | 247 | 1,729 | 3,089 | 21,623 | 40,157 | 58,691 | 281,099 | 410,837 | 762,983 | 5,340,881 |
| -1 | -7 | -13 | -19 | -91 | -133 | -247 | -1,729 | -3,089 | -21,623 | -40,157 | -58,691 | -281,099 | -410,837 | -762,983 | -5,340,881 |
