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 333,313,355, 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 | 333,313,355 | |
| -1 | -333,313,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 333,313,355.
Example:
1 x 333,313,355 = 333,313,355
and
-1 x -333,313,355 = 333,313,355
Notice both answers equal 333,313,355
With that explanation out of the way, let's continue. Next, we take the number 333,313,355 and divide it by 2:
333,313,355 ÷ 2 = 166,656,677.5
If the quotient is a whole number, then 2 and 166,656,677.5 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 | 333,313,355 | |
| -1 | -333,313,355 |
Now, we try dividing 333,313,355 by 3:
333,313,355 ÷ 3 = 111,104,451.6667
If the quotient is a whole number, then 3 and 111,104,451.6667 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 | 333,313,355 | |
| -1 | -333,313,355 |
Let's try dividing by 4:
333,313,355 ÷ 4 = 83,328,338.75
If the quotient is a whole number, then 4 and 83,328,338.75 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 | 333,313,355 | |
| -1 | 333,313,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 157 | 785 | 3,611 | 18,055 | 18,461 | 92,305 | 424,603 | 2,123,015 | 2,898,377 | 14,491,885 | 66,662,671 | 333,313,355 |
| -1 | -5 | -23 | -115 | -157 | -785 | -3,611 | -18,055 | -18,461 | -92,305 | -424,603 | -2,123,015 | -2,898,377 | -14,491,885 | -66,662,671 | -333,313,355 |
