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 132,031,343, 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 | 132,031,343 | |
-1 | -132,031,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 132,031,343.
Example:
1 x 132,031,343 = 132,031,343
and
-1 x -132,031,343 = 132,031,343
Notice both answers equal 132,031,343
With that explanation out of the way, let's continue. Next, we take the number 132,031,343 and divide it by 2:
132,031,343 ÷ 2 = 66,015,671.5
If the quotient is a whole number, then 2 and 66,015,671.5 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 | 132,031,343 | |
-1 | -132,031,343 |
Now, we try dividing 132,031,343 by 3:
132,031,343 ÷ 3 = 44,010,447.6667
If the quotient is a whole number, then 3 and 44,010,447.6667 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 | 132,031,343 | |
-1 | -132,031,343 |
Let's try dividing by 4:
132,031,343 ÷ 4 = 33,007,835.75
If the quotient is a whole number, then 4 and 33,007,835.75 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 | 132,031,343 | |
-1 | 132,031,343 |
If you did it right, you will end up with this table:
1 | 2,903 | 45,481 | 132,031,343 |
-1 | -2,903 | -45,481 | -132,031,343 |
