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 615,442,595, 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 | 615,442,595 | |
| -1 | -615,442,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 615,442,595.
Example:
1 x 615,442,595 = 615,442,595
and
-1 x -615,442,595 = 615,442,595
Notice both answers equal 615,442,595
With that explanation out of the way, let's continue. Next, we take the number 615,442,595 and divide it by 2:
615,442,595 ÷ 2 = 307,721,297.5
If the quotient is a whole number, then 2 and 307,721,297.5 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 | 615,442,595 | |
| -1 | -615,442,595 |
Now, we try dividing 615,442,595 by 3:
615,442,595 ÷ 3 = 205,147,531.6667
If the quotient is a whole number, then 3 and 205,147,531.6667 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 | 615,442,595 | |
| -1 | -615,442,595 |
Let's try dividing by 4:
615,442,595 ÷ 4 = 153,860,648.75
If the quotient is a whole number, then 4 and 153,860,648.75 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 | 615,442,595 | |
| -1 | 615,442,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 167 | 205 | 835 | 6,847 | 17,977 | 34,235 | 89,885 | 737,057 | 3,002,159 | 3,685,285 | 15,010,795 | 123,088,519 | 615,442,595 |
| -1 | -5 | -41 | -167 | -205 | -835 | -6,847 | -17,977 | -34,235 | -89,885 | -737,057 | -3,002,159 | -3,685,285 | -15,010,795 | -123,088,519 | -615,442,595 |
