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 606,505,615, 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 | 606,505,615 | |
| -1 | -606,505,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 606,505,615.
Example:
1 x 606,505,615 = 606,505,615
and
-1 x -606,505,615 = 606,505,615
Notice both answers equal 606,505,615
With that explanation out of the way, let's continue. Next, we take the number 606,505,615 and divide it by 2:
606,505,615 ÷ 2 = 303,252,807.5
If the quotient is a whole number, then 2 and 303,252,807.5 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 | 606,505,615 | |
| -1 | -606,505,615 |
Now, we try dividing 606,505,615 by 3:
606,505,615 ÷ 3 = 202,168,538.3333
If the quotient is a whole number, then 3 and 202,168,538.3333 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 | 606,505,615 | |
| -1 | -606,505,615 |
Let's try dividing by 4:
606,505,615 ÷ 4 = 151,626,403.75
If the quotient is a whole number, then 4 and 151,626,403.75 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 | 606,505,615 | |
| -1 | 606,505,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 263 | 305 | 1,315 | 7,561 | 16,043 | 37,805 | 80,215 | 461,221 | 1,988,543 | 2,306,105 | 9,942,715 | 121,301,123 | 606,505,615 |
| -1 | -5 | -61 | -263 | -305 | -1,315 | -7,561 | -16,043 | -37,805 | -80,215 | -461,221 | -1,988,543 | -2,306,105 | -9,942,715 | -121,301,123 | -606,505,615 |
