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 303,135,587, 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 | 303,135,587 | |
-1 | -303,135,587 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,135,587.
Example:
1 x 303,135,587 = 303,135,587
and
-1 x -303,135,587 = 303,135,587
Notice both answers equal 303,135,587
With that explanation out of the way, let's continue. Next, we take the number 303,135,587 and divide it by 2:
303,135,587 ÷ 2 = 151,567,793.5
If the quotient is a whole number, then 2 and 151,567,793.5 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 | 303,135,587 | |
-1 | -303,135,587 |
Now, we try dividing 303,135,587 by 3:
303,135,587 ÷ 3 = 101,045,195.6667
If the quotient is a whole number, then 3 and 101,045,195.6667 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 | 303,135,587 | |
-1 | -303,135,587 |
Let's try dividing by 4:
303,135,587 ÷ 4 = 75,783,896.75
If the quotient is a whole number, then 4 and 75,783,896.75 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 | 303,135,587 | |
-1 | 303,135,587 |
If you did it right, you will end up with this table:
1 | 2,137 | 141,851 | 303,135,587 |
-1 | -2,137 | -141,851 | -303,135,587 |
