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 605,320,331, 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 | 605,320,331 | |
| -1 | -605,320,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 605,320,331.
Example:
1 x 605,320,331 = 605,320,331
and
-1 x -605,320,331 = 605,320,331
Notice both answers equal 605,320,331
With that explanation out of the way, let's continue. Next, we take the number 605,320,331 and divide it by 2:
605,320,331 ÷ 2 = 302,660,165.5
If the quotient is a whole number, then 2 and 302,660,165.5 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 | 605,320,331 | |
| -1 | -605,320,331 |
Now, we try dividing 605,320,331 by 3:
605,320,331 ÷ 3 = 201,773,443.6667
If the quotient is a whole number, then 3 and 201,773,443.6667 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 | 605,320,331 | |
| -1 | -605,320,331 |
Let's try dividing by 4:
605,320,331 ÷ 4 = 151,330,082.75
If the quotient is a whole number, then 4 and 151,330,082.75 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 | 605,320,331 | |
| -1 | 605,320,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 43 | 77 | 301 | 473 | 3,311 | 182,821 | 1,279,747 | 2,011,031 | 7,861,303 | 14,077,217 | 55,029,121 | 86,474,333 | 605,320,331 |
| -1 | -7 | -11 | -43 | -77 | -301 | -473 | -3,311 | -182,821 | -1,279,747 | -2,011,031 | -7,861,303 | -14,077,217 | -55,029,121 | -86,474,333 | -605,320,331 |
