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 331,454,633, 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 | 331,454,633 | |
| -1 | -331,454,633 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,454,633.
Example:
1 x 331,454,633 = 331,454,633
and
-1 x -331,454,633 = 331,454,633
Notice both answers equal 331,454,633
With that explanation out of the way, let's continue. Next, we take the number 331,454,633 and divide it by 2:
331,454,633 ÷ 2 = 165,727,316.5
If the quotient is a whole number, then 2 and 165,727,316.5 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 | 331,454,633 | |
| -1 | -331,454,633 |
Now, we try dividing 331,454,633 by 3:
331,454,633 ÷ 3 = 110,484,877.6667
If the quotient is a whole number, then 3 and 110,484,877.6667 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 | 331,454,633 | |
| -1 | -331,454,633 |
Let's try dividing by 4:
331,454,633 ÷ 4 = 82,863,658.25
If the quotient is a whole number, then 4 and 82,863,658.25 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 | 331,454,633 | |
| -1 | 331,454,633 |
If you did it right, you will end up with this table:
| 1 | 23 | 53 | 127 | 1,219 | 2,141 | 2,921 | 6,731 | 49,243 | 113,473 | 154,813 | 271,907 | 2,609,879 | 6,253,861 | 14,411,071 | 331,454,633 |
| -1 | -23 | -53 | -127 | -1,219 | -2,141 | -2,921 | -6,731 | -49,243 | -113,473 | -154,813 | -271,907 | -2,609,879 | -6,253,861 | -14,411,071 | -331,454,633 |
