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 605,159,999, 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 | 605,159,999 | |
| -1 | -605,159,999 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 605,159,999.
Example:
1 x 605,159,999 = 605,159,999
and
-1 x -605,159,999 = 605,159,999
Notice both answers equal 605,159,999
With that explanation out of the way, let's continue. Next, we take the number 605,159,999 and divide it by 2:
605,159,999 ÷ 2 = 302,579,999.5
If the quotient is a whole number, then 2 and 302,579,999.5 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 | 605,159,999 | |
| -1 | -605,159,999 |
Now, we try dividing 605,159,999 by 3:
605,159,999 ÷ 3 = 201,719,999.6667
If the quotient is a whole number, then 3 and 201,719,999.6667 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 | 605,159,999 | |
| -1 | -605,159,999 |
Let's try dividing by 4:
605,159,999 ÷ 4 = 151,289,999.75
If the quotient is a whole number, then 4 and 151,289,999.75 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 | 605,159,999 | |
| -1 | 605,159,999 |
If you did it right, you will end up with this table:
| 1 | 17 | 73 | 337 | 1,241 | 1,447 | 5,729 | 24,599 | 24,601 | 105,631 | 418,217 | 487,639 | 1,795,727 | 8,289,863 | 35,597,647 | 605,159,999 |
| -1 | -17 | -73 | -337 | -1,241 | -1,447 | -5,729 | -24,599 | -24,601 | -105,631 | -418,217 | -487,639 | -1,795,727 | -8,289,863 | -35,597,647 | -605,159,999 |
