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 333,154,331, 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 | 333,154,331 | |
-1 | -333,154,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 333,154,331.
Example:
1 x 333,154,331 = 333,154,331
and
-1 x -333,154,331 = 333,154,331
Notice both answers equal 333,154,331
With that explanation out of the way, let's continue. Next, we take the number 333,154,331 and divide it by 2:
333,154,331 ÷ 2 = 166,577,165.5
If the quotient is a whole number, then 2 and 166,577,165.5 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 | 333,154,331 | |
-1 | -333,154,331 |
Now, we try dividing 333,154,331 by 3:
333,154,331 ÷ 3 = 111,051,443.6667
If the quotient is a whole number, then 3 and 111,051,443.6667 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 | 333,154,331 | |
-1 | -333,154,331 |
Let's try dividing by 4:
333,154,331 ÷ 4 = 83,288,582.75
If the quotient is a whole number, then 4 and 83,288,582.75 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 | 333,154,331 | |
-1 | 333,154,331 |
If you did it right, you will end up with this table:
1 | 1,373 | 242,647 | 333,154,331 |
-1 | -1,373 | -242,647 | -333,154,331 |
