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 331,204,735, 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 | 331,204,735 | |
| -1 | -331,204,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,204,735.
Example:
1 x 331,204,735 = 331,204,735
and
-1 x -331,204,735 = 331,204,735
Notice both answers equal 331,204,735
With that explanation out of the way, let's continue. Next, we take the number 331,204,735 and divide it by 2:
331,204,735 ÷ 2 = 165,602,367.5
If the quotient is a whole number, then 2 and 165,602,367.5 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 | 331,204,735 | |
| -1 | -331,204,735 |
Now, we try dividing 331,204,735 by 3:
331,204,735 ÷ 3 = 110,401,578.3333
If the quotient is a whole number, then 3 and 110,401,578.3333 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 | 331,204,735 | |
| -1 | -331,204,735 |
Let's try dividing by 4:
331,204,735 ÷ 4 = 82,801,183.75
If the quotient is a whole number, then 4 and 82,801,183.75 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 | 331,204,735 | |
| -1 | 331,204,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 395 | 463 | 1,811 | 2,315 | 9,055 | 36,577 | 143,069 | 182,885 | 715,345 | 838,493 | 4,192,465 | 66,240,947 | 331,204,735 |
| -1 | -5 | -79 | -395 | -463 | -1,811 | -2,315 | -9,055 | -36,577 | -143,069 | -182,885 | -715,345 | -838,493 | -4,192,465 | -66,240,947 | -331,204,735 |
