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 331,355,435, 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 | 331,355,435 | |
| -1 | -331,355,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,355,435.
Example:
1 x 331,355,435 = 331,355,435
and
-1 x -331,355,435 = 331,355,435
Notice both answers equal 331,355,435
With that explanation out of the way, let's continue. Next, we take the number 331,355,435 and divide it by 2:
331,355,435 ÷ 2 = 165,677,717.5
If the quotient is a whole number, then 2 and 165,677,717.5 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 | 331,355,435 | |
| -1 | -331,355,435 |
Now, we try dividing 331,355,435 by 3:
331,355,435 ÷ 3 = 110,451,811.6667
If the quotient is a whole number, then 3 and 110,451,811.6667 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 | 331,355,435 | |
| -1 | -331,355,435 |
Let's try dividing by 4:
331,355,435 ÷ 4 = 82,838,858.75
If the quotient is a whole number, then 4 and 82,838,858.75 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 | 331,355,435 | |
| -1 | 331,355,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 479 | 2,395 | 4,463 | 14,849 | 22,315 | 74,245 | 138,353 | 691,765 | 2,137,777 | 10,688,885 | 66,271,087 | 331,355,435 |
| -1 | -5 | -31 | -155 | -479 | -2,395 | -4,463 | -14,849 | -22,315 | -74,245 | -138,353 | -691,765 | -2,137,777 | -10,688,885 | -66,271,087 | -331,355,435 |
