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 331,550,651, 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 | 331,550,651 | |
-1 | -331,550,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 331,550,651.
Example:
1 x 331,550,651 = 331,550,651
and
-1 x -331,550,651 = 331,550,651
Notice both answers equal 331,550,651
With that explanation out of the way, let's continue. Next, we take the number 331,550,651 and divide it by 2:
331,550,651 ÷ 2 = 165,775,325.5
If the quotient is a whole number, then 2 and 165,775,325.5 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 | 331,550,651 | |
-1 | -331,550,651 |
Now, we try dividing 331,550,651 by 3:
331,550,651 ÷ 3 = 110,516,883.6667
If the quotient is a whole number, then 3 and 110,516,883.6667 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 | 331,550,651 | |
-1 | -331,550,651 |
Let's try dividing by 4:
331,550,651 ÷ 4 = 82,887,662.75
If the quotient is a whole number, then 4 and 82,887,662.75 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 | 331,550,651 | |
-1 | 331,550,651 |
If you did it right, you will end up with this table:
1 | 131 | 2,530,921 | 331,550,651 |
-1 | -131 | -2,530,921 | -331,550,651 |
