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 608,147,015, 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 | 608,147,015 | |
| -1 | -608,147,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 608,147,015.
Example:
1 x 608,147,015 = 608,147,015
and
-1 x -608,147,015 = 608,147,015
Notice both answers equal 608,147,015
With that explanation out of the way, let's continue. Next, we take the number 608,147,015 and divide it by 2:
608,147,015 ÷ 2 = 304,073,507.5
If the quotient is a whole number, then 2 and 304,073,507.5 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 | 608,147,015 | |
| -1 | -608,147,015 |
Now, we try dividing 608,147,015 by 3:
608,147,015 ÷ 3 = 202,715,671.6667
If the quotient is a whole number, then 3 and 202,715,671.6667 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 | 608,147,015 | |
| -1 | -608,147,015 |
Let's try dividing by 4:
608,147,015 ÷ 4 = 152,036,753.75
If the quotient is a whole number, then 4 and 152,036,753.75 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 | 608,147,015 | |
| -1 | 608,147,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 523 | 2,615 | 3,661 | 18,305 | 33,223 | 166,115 | 232,561 | 1,162,805 | 17,375,629 | 86,878,145 | 121,629,403 | 608,147,015 |
| -1 | -5 | -7 | -35 | -523 | -2,615 | -3,661 | -18,305 | -33,223 | -166,115 | -232,561 | -1,162,805 | -17,375,629 | -86,878,145 | -121,629,403 | -608,147,015 |
