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 322,999,999, 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 | 322,999,999 | |
| -1 | -322,999,999 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 322,999,999.
Example:
1 x 322,999,999 = 322,999,999
and
-1 x -322,999,999 = 322,999,999
Notice both answers equal 322,999,999
With that explanation out of the way, let's continue. Next, we take the number 322,999,999 and divide it by 2:
322,999,999 ÷ 2 = 161,499,999.5
If the quotient is a whole number, then 2 and 161,499,999.5 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 | 322,999,999 | |
| -1 | -322,999,999 |
Now, we try dividing 322,999,999 by 3:
322,999,999 ÷ 3 = 107,666,666.3333
If the quotient is a whole number, then 3 and 107,666,666.3333 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 | 322,999,999 | |
| -1 | -322,999,999 |
Let's try dividing by 4:
322,999,999 ÷ 4 = 80,749,999.75
If the quotient is a whole number, then 4 and 80,749,999.75 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 | 322,999,999 | |
| -1 | 322,999,999 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 139 | 203 | 973 | 4,031 | 11,447 | 28,217 | 80,129 | 331,963 | 1,591,133 | 2,323,741 | 11,137,931 | 46,142,857 | 322,999,999 |
| -1 | -7 | -29 | -139 | -203 | -973 | -4,031 | -11,447 | -28,217 | -80,129 | -331,963 | -1,591,133 | -2,323,741 | -11,137,931 | -46,142,857 | -322,999,999 |
