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 333,210,319, 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 | 333,210,319 | |
| -1 | -333,210,319 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 333,210,319.
Example:
1 x 333,210,319 = 333,210,319
and
-1 x -333,210,319 = 333,210,319
Notice both answers equal 333,210,319
With that explanation out of the way, let's continue. Next, we take the number 333,210,319 and divide it by 2:
333,210,319 ÷ 2 = 166,605,159.5
If the quotient is a whole number, then 2 and 166,605,159.5 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 | 333,210,319 | |
| -1 | -333,210,319 |
Now, we try dividing 333,210,319 by 3:
333,210,319 ÷ 3 = 111,070,106.3333
If the quotient is a whole number, then 3 and 111,070,106.3333 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 | 333,210,319 | |
| -1 | -333,210,319 |
Let's try dividing by 4:
333,210,319 ÷ 4 = 83,302,579.75
If the quotient is a whole number, then 4 and 83,302,579.75 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 | 333,210,319 | |
| -1 | 333,210,319 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 29 | 221 | 377 | 493 | 6,409 | 51,991 | 675,883 | 883,847 | 1,507,739 | 11,490,011 | 19,600,607 | 25,631,563 | 333,210,319 |
| -1 | -13 | -17 | -29 | -221 | -377 | -493 | -6,409 | -51,991 | -675,883 | -883,847 | -1,507,739 | -11,490,011 | -19,600,607 | -25,631,563 | -333,210,319 |
