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 6,081,215, 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 | 6,081,215 | |
| -1 | -6,081,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 6,081,215.
Example:
1 x 6,081,215 = 6,081,215
and
-1 x -6,081,215 = 6,081,215
Notice both answers equal 6,081,215
With that explanation out of the way, let's continue. Next, we take the number 6,081,215 and divide it by 2:
6,081,215 ÷ 2 = 3,040,607.5
If the quotient is a whole number, then 2 and 3,040,607.5 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 | 6,081,215 | |
| -1 | -6,081,215 |
Now, we try dividing 6,081,215 by 3:
6,081,215 ÷ 3 = 2,027,071.6667
If the quotient is a whole number, then 3 and 2,027,071.6667 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 | 6,081,215 | |
| -1 | -6,081,215 |
Let's try dividing by 4:
6,081,215 ÷ 4 = 1,520,303.75
If the quotient is a whole number, then 4 and 1,520,303.75 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 | 6,081,215 | |
| -1 | 6,081,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 293 | 593 | 1,465 | 2,051 | 2,965 | 4,151 | 10,255 | 20,755 | 173,749 | 868,745 | 1,216,243 | 6,081,215 |
| -1 | -5 | -7 | -35 | -293 | -593 | -1,465 | -2,051 | -2,965 | -4,151 | -10,255 | -20,755 | -173,749 | -868,745 | -1,216,243 | -6,081,215 |
