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 328,324,747, 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 | 328,324,747 | |
| -1 | -328,324,747 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 328,324,747.
Example:
1 x 328,324,747 = 328,324,747
and
-1 x -328,324,747 = 328,324,747
Notice both answers equal 328,324,747
With that explanation out of the way, let's continue. Next, we take the number 328,324,747 and divide it by 2:
328,324,747 ÷ 2 = 164,162,373.5
If the quotient is a whole number, then 2 and 164,162,373.5 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 | 328,324,747 | |
| -1 | -328,324,747 |
Now, we try dividing 328,324,747 by 3:
328,324,747 ÷ 3 = 109,441,582.3333
If the quotient is a whole number, then 3 and 109,441,582.3333 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 | 328,324,747 | |
| -1 | -328,324,747 |
Let's try dividing by 4:
328,324,747 ÷ 4 = 82,081,186.75
If the quotient is a whole number, then 4 and 82,081,186.75 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 | 328,324,747 | |
| -1 | 328,324,747 |
If you did it right, you will end up with this table:
| 1 | 23 | 29 | 137 | 667 | 3,151 | 3,593 | 3,973 | 82,639 | 91,379 | 104,197 | 492,241 | 2,396,531 | 11,321,543 | 14,274,989 | 328,324,747 |
| -1 | -23 | -29 | -137 | -667 | -3,151 | -3,593 | -3,973 | -82,639 | -91,379 | -104,197 | -492,241 | -2,396,531 | -11,321,543 | -14,274,989 | -328,324,747 |
