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 333,542,209, 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 | 333,542,209 | |
| -1 | -333,542,209 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 333,542,209.
Example:
1 x 333,542,209 = 333,542,209
and
-1 x -333,542,209 = 333,542,209
Notice both answers equal 333,542,209
With that explanation out of the way, let's continue. Next, we take the number 333,542,209 and divide it by 2:
333,542,209 ÷ 2 = 166,771,104.5
If the quotient is a whole number, then 2 and 166,771,104.5 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 | 333,542,209 | |
| -1 | -333,542,209 |
Now, we try dividing 333,542,209 by 3:
333,542,209 ÷ 3 = 111,180,736.3333
If the quotient is a whole number, then 3 and 111,180,736.3333 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 | 333,542,209 | |
| -1 | -333,542,209 |
Let's try dividing by 4:
333,542,209 ÷ 4 = 83,385,552.25
If the quotient is a whole number, then 4 and 83,385,552.25 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 | 333,542,209 | |
| -1 | 333,542,209 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 1,001 | 333,209 | 2,332,463 | 3,665,299 | 4,331,717 | 25,657,093 | 30,322,019 | 47,648,887 | 333,542,209 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -1,001 | -333,209 | -2,332,463 | -3,665,299 | -4,331,717 | -25,657,093 | -30,322,019 | -47,648,887 | -333,542,209 |
