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 611,332,015, 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 | 611,332,015 | |
| -1 | -611,332,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 611,332,015.
Example:
1 x 611,332,015 = 611,332,015
and
-1 x -611,332,015 = 611,332,015
Notice both answers equal 611,332,015
With that explanation out of the way, let's continue. Next, we take the number 611,332,015 and divide it by 2:
611,332,015 ÷ 2 = 305,666,007.5
If the quotient is a whole number, then 2 and 305,666,007.5 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 | 611,332,015 | |
| -1 | -611,332,015 |
Now, we try dividing 611,332,015 by 3:
611,332,015 ÷ 3 = 203,777,338.3333
If the quotient is a whole number, then 3 and 203,777,338.3333 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 | 611,332,015 | |
| -1 | -611,332,015 |
Let's try dividing by 4:
611,332,015 ÷ 4 = 152,833,003.75
If the quotient is a whole number, then 4 and 152,833,003.75 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 | 611,332,015 | |
| -1 | 611,332,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,039 | 5,195 | 7,273 | 16,811 | 36,365 | 84,055 | 117,677 | 588,385 | 17,466,629 | 87,333,145 | 122,266,403 | 611,332,015 |
| -1 | -5 | -7 | -35 | -1,039 | -5,195 | -7,273 | -16,811 | -36,365 | -84,055 | -117,677 | -588,385 | -17,466,629 | -87,333,145 | -122,266,403 | -611,332,015 |
