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 321,244,343, 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 | 321,244,343 | |
| -1 | -321,244,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,244,343.
Example:
1 x 321,244,343 = 321,244,343
and
-1 x -321,244,343 = 321,244,343
Notice both answers equal 321,244,343
With that explanation out of the way, let's continue. Next, we take the number 321,244,343 and divide it by 2:
321,244,343 ÷ 2 = 160,622,171.5
If the quotient is a whole number, then 2 and 160,622,171.5 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 | 321,244,343 | |
| -1 | -321,244,343 |
Now, we try dividing 321,244,343 by 3:
321,244,343 ÷ 3 = 107,081,447.6667
If the quotient is a whole number, then 3 and 107,081,447.6667 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 | 321,244,343 | |
| -1 | -321,244,343 |
Let's try dividing by 4:
321,244,343 ÷ 4 = 80,311,085.75
If the quotient is a whole number, then 4 and 80,311,085.75 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 | 321,244,343 | |
| -1 | 321,244,343 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 49 | 89 | 133 | 623 | 931 | 1,691 | 3,877 | 4,361 | 11,837 | 27,139 | 73,663 | 82,859 | 189,973 | 345,053 | 515,641 | 2,415,371 | 3,609,487 | 6,556,007 | 16,907,597 | 45,892,049 | 321,244,343 |
| -1 | -7 | -19 | -49 | -89 | -133 | -623 | -931 | -1,691 | -3,877 | -4,361 | -11,837 | -27,139 | -73,663 | -82,859 | -189,973 | -345,053 | -515,641 | -2,415,371 | -3,609,487 | -6,556,007 | -16,907,597 | -45,892,049 | -321,244,343 |
