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 333,508,145, 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 | 333,508,145 | |
| -1 | -333,508,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 333,508,145.
Example:
1 x 333,508,145 = 333,508,145
and
-1 x -333,508,145 = 333,508,145
Notice both answers equal 333,508,145
With that explanation out of the way, let's continue. Next, we take the number 333,508,145 and divide it by 2:
333,508,145 ÷ 2 = 166,754,072.5
If the quotient is a whole number, then 2 and 166,754,072.5 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 | 333,508,145 | |
| -1 | -333,508,145 |
Now, we try dividing 333,508,145 by 3:
333,508,145 ÷ 3 = 111,169,381.6667
If the quotient is a whole number, then 3 and 111,169,381.6667 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 | 333,508,145 | |
| -1 | -333,508,145 |
Let's try dividing by 4:
333,508,145 ÷ 4 = 83,377,036.25
If the quotient is a whole number, then 4 and 83,377,036.25 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 | 333,508,145 | |
| -1 | 333,508,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 461 | 2,305 | 3,529 | 17,645 | 18,901 | 94,505 | 144,689 | 723,445 | 1,626,869 | 8,134,345 | 66,701,629 | 333,508,145 |
| -1 | -5 | -41 | -205 | -461 | -2,305 | -3,529 | -17,645 | -18,901 | -94,505 | -144,689 | -723,445 | -1,626,869 | -8,134,345 | -66,701,629 | -333,508,145 |
