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 605,232,715, 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 | 605,232,715 | |
| -1 | -605,232,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 605,232,715.
Example:
1 x 605,232,715 = 605,232,715
and
-1 x -605,232,715 = 605,232,715
Notice both answers equal 605,232,715
With that explanation out of the way, let's continue. Next, we take the number 605,232,715 and divide it by 2:
605,232,715 ÷ 2 = 302,616,357.5
If the quotient is a whole number, then 2 and 302,616,357.5 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 | 605,232,715 | |
| -1 | -605,232,715 |
Now, we try dividing 605,232,715 by 3:
605,232,715 ÷ 3 = 201,744,238.3333
If the quotient is a whole number, then 3 and 201,744,238.3333 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 | 605,232,715 | |
| -1 | -605,232,715 |
Let's try dividing by 4:
605,232,715 ÷ 4 = 151,308,178.75
If the quotient is a whole number, then 4 and 151,308,178.75 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 | 605,232,715 | |
| -1 | 605,232,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 173 | 359 | 865 | 1,795 | 1,949 | 9,745 | 62,107 | 310,535 | 337,177 | 699,691 | 1,685,885 | 3,498,455 | 121,046,543 | 605,232,715 |
| -1 | -5 | -173 | -359 | -865 | -1,795 | -1,949 | -9,745 | -62,107 | -310,535 | -337,177 | -699,691 | -1,685,885 | -3,498,455 | -121,046,543 | -605,232,715 |
