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 605,320,235, 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 | 605,320,235 | |
| -1 | -605,320,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 605,320,235.
Example:
1 x 605,320,235 = 605,320,235
and
-1 x -605,320,235 = 605,320,235
Notice both answers equal 605,320,235
With that explanation out of the way, let's continue. Next, we take the number 605,320,235 and divide it by 2:
605,320,235 ÷ 2 = 302,660,117.5
If the quotient is a whole number, then 2 and 302,660,117.5 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 | 605,320,235 | |
| -1 | -605,320,235 |
Now, we try dividing 605,320,235 by 3:
605,320,235 ÷ 3 = 201,773,411.6667
If the quotient is a whole number, then 3 and 201,773,411.6667 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 | 605,320,235 | |
| -1 | -605,320,235 |
Let's try dividing by 4:
605,320,235 ÷ 4 = 151,330,058.75
If the quotient is a whole number, then 4 and 151,330,058.75 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 | 605,320,235 | |
| -1 | 605,320,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 59 | 65 | 295 | 767 | 3,835 | 157,841 | 789,205 | 2,051,933 | 9,312,619 | 10,259,665 | 46,563,095 | 121,064,047 | 605,320,235 |
| -1 | -5 | -13 | -59 | -65 | -295 | -767 | -3,835 | -157,841 | -789,205 | -2,051,933 | -9,312,619 | -10,259,665 | -46,563,095 | -121,064,047 | -605,320,235 |
