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 311,131,013, 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 | 311,131,013 | |
-1 | -311,131,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 311,131,013.
Example:
1 x 311,131,013 = 311,131,013
and
-1 x -311,131,013 = 311,131,013
Notice both answers equal 311,131,013
With that explanation out of the way, let's continue. Next, we take the number 311,131,013 and divide it by 2:
311,131,013 ÷ 2 = 155,565,506.5
If the quotient is a whole number, then 2 and 155,565,506.5 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 | 311,131,013 | |
-1 | -311,131,013 |
Now, we try dividing 311,131,013 by 3:
311,131,013 ÷ 3 = 103,710,337.6667
If the quotient is a whole number, then 3 and 103,710,337.6667 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 | 311,131,013 | |
-1 | -311,131,013 |
Let's try dividing by 4:
311,131,013 ÷ 4 = 77,782,753.25
If the quotient is a whole number, then 4 and 77,782,753.25 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 | 311,131,013 | |
-1 | 311,131,013 |
If you did it right, you will end up with this table:
1 | 59 | 5,273,407 | 311,131,013 |
-1 | -59 | -5,273,407 | -311,131,013 |
