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 333,364,421, 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 | 333,364,421 | |
| -1 | -333,364,421 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 333,364,421.
Example:
1 x 333,364,421 = 333,364,421
and
-1 x -333,364,421 = 333,364,421
Notice both answers equal 333,364,421
With that explanation out of the way, let's continue. Next, we take the number 333,364,421 and divide it by 2:
333,364,421 ÷ 2 = 166,682,210.5
If the quotient is a whole number, then 2 and 166,682,210.5 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 | 333,364,421 | |
| -1 | -333,364,421 |
Now, we try dividing 333,364,421 by 3:
333,364,421 ÷ 3 = 111,121,473.6667
If the quotient is a whole number, then 3 and 111,121,473.6667 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 | 333,364,421 | |
| -1 | -333,364,421 |
Let's try dividing by 4:
333,364,421 ÷ 4 = 83,341,105.25
If the quotient is a whole number, then 4 and 83,341,105.25 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 | 333,364,421 | |
| -1 | 333,364,421 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 403 | 761 | 1,087 | 9,893 | 14,131 | 23,591 | 33,697 | 306,683 | 438,061 | 827,207 | 10,753,691 | 25,643,417 | 333,364,421 |
| -1 | -13 | -31 | -403 | -761 | -1,087 | -9,893 | -14,131 | -23,591 | -33,697 | -306,683 | -438,061 | -827,207 | -10,753,691 | -25,643,417 | -333,364,421 |
