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 328,125,823, 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 | 328,125,823 | |
| -1 | -328,125,823 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 328,125,823.
Example:
1 x 328,125,823 = 328,125,823
and
-1 x -328,125,823 = 328,125,823
Notice both answers equal 328,125,823
With that explanation out of the way, let's continue. Next, we take the number 328,125,823 and divide it by 2:
328,125,823 ÷ 2 = 164,062,911.5
If the quotient is a whole number, then 2 and 164,062,911.5 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 | 328,125,823 | |
| -1 | -328,125,823 |
Now, we try dividing 328,125,823 by 3:
328,125,823 ÷ 3 = 109,375,274.3333
If the quotient is a whole number, then 3 and 109,375,274.3333 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 | 328,125,823 | |
| -1 | -328,125,823 |
Let's try dividing by 4:
328,125,823 ÷ 4 = 82,031,455.75
If the quotient is a whole number, then 4 and 82,031,455.75 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 | 328,125,823 | |
| -1 | 328,125,823 |
If you did it right, you will end up with this table:
| 1 | 17 | 89 | 137 | 1,513 | 1,583 | 2,329 | 12,193 | 26,911 | 140,887 | 207,281 | 216,871 | 2,395,079 | 3,686,807 | 19,301,519 | 328,125,823 |
| -1 | -17 | -89 | -137 | -1,513 | -1,583 | -2,329 | -12,193 | -26,911 | -140,887 | -207,281 | -216,871 | -2,395,079 | -3,686,807 | -19,301,519 | -328,125,823 |
