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 313,333,321, 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 | 313,333,321 | |
| -1 | -313,333,321 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 313,333,321.
Example:
1 x 313,333,321 = 313,333,321
and
-1 x -313,333,321 = 313,333,321
Notice both answers equal 313,333,321
With that explanation out of the way, let's continue. Next, we take the number 313,333,321 and divide it by 2:
313,333,321 ÷ 2 = 156,666,660.5
If the quotient is a whole number, then 2 and 156,666,660.5 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 | 313,333,321 | |
| -1 | -313,333,321 |
Now, we try dividing 313,333,321 by 3:
313,333,321 ÷ 3 = 104,444,440.3333
If the quotient is a whole number, then 3 and 104,444,440.3333 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 | 313,333,321 | |
| -1 | -313,333,321 |
Let's try dividing by 4:
313,333,321 ÷ 4 = 78,333,330.25
If the quotient is a whole number, then 4 and 78,333,330.25 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 | 313,333,321 | |
| -1 | 313,333,321 |
If you did it right, you will end up with this table:
| 1 | 7 | 227 | 293 | 673 | 1,589 | 2,051 | 4,711 | 66,511 | 152,771 | 197,189 | 465,577 | 1,069,397 | 1,380,323 | 44,761,903 | 313,333,321 |
| -1 | -7 | -227 | -293 | -673 | -1,589 | -2,051 | -4,711 | -66,511 | -152,771 | -197,189 | -465,577 | -1,069,397 | -1,380,323 | -44,761,903 | -313,333,321 |
