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 664,065,259, 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 | 664,065,259 | |
| -1 | -664,065,259 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 664,065,259.
Example:
1 x 664,065,259 = 664,065,259
and
-1 x -664,065,259 = 664,065,259
Notice both answers equal 664,065,259
With that explanation out of the way, let's continue. Next, we take the number 664,065,259 and divide it by 2:
664,065,259 ÷ 2 = 332,032,629.5
If the quotient is a whole number, then 2 and 332,032,629.5 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 | 664,065,259 | |
| -1 | -664,065,259 |
Now, we try dividing 664,065,259 by 3:
664,065,259 ÷ 3 = 221,355,086.3333
If the quotient is a whole number, then 3 and 221,355,086.3333 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 | 664,065,259 | |
| -1 | -664,065,259 |
Let's try dividing by 4:
664,065,259 ÷ 4 = 166,016,314.75
If the quotient is a whole number, then 4 and 166,016,314.75 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 | 664,065,259 | |
| -1 | 664,065,259 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 2,063 | 2,251 | 22,693 | 24,761 | 26,819 | 29,263 | 295,009 | 321,893 | 4,643,813 | 51,081,943 | 60,369,569 | 664,065,259 |
| -1 | -11 | -13 | -143 | -2,063 | -2,251 | -22,693 | -24,761 | -26,819 | -29,263 | -295,009 | -321,893 | -4,643,813 | -51,081,943 | -60,369,569 | -664,065,259 |
