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 664,135,043, 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 | 664,135,043 | |
| -1 | -664,135,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 664,135,043.
Example:
1 x 664,135,043 = 664,135,043
and
-1 x -664,135,043 = 664,135,043
Notice both answers equal 664,135,043
With that explanation out of the way, let's continue. Next, we take the number 664,135,043 and divide it by 2:
664,135,043 ÷ 2 = 332,067,521.5
If the quotient is a whole number, then 2 and 332,067,521.5 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 | 664,135,043 | |
| -1 | -664,135,043 |
Now, we try dividing 664,135,043 by 3:
664,135,043 ÷ 3 = 221,378,347.6667
If the quotient is a whole number, then 3 and 221,378,347.6667 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 | 664,135,043 | |
| -1 | -664,135,043 |
Let's try dividing by 4:
664,135,043 ÷ 4 = 166,033,760.75
If the quotient is a whole number, then 4 and 166,033,760.75 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 | 664,135,043 | |
| -1 | 664,135,043 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 43 | 143 | 473 | 559 | 6,149 | 108,007 | 1,188,077 | 1,404,091 | 4,644,301 | 15,445,001 | 51,087,311 | 60,375,913 | 664,135,043 |
| -1 | -11 | -13 | -43 | -143 | -473 | -559 | -6,149 | -108,007 | -1,188,077 | -1,404,091 | -4,644,301 | -15,445,001 | -51,087,311 | -60,375,913 | -664,135,043 |
