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 30,503, 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 | 30,503 | |
-1 | -30,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,503.
Example:
1 x 30,503 = 30,503
and
-1 x -30,503 = 30,503
Notice both answers equal 30,503
With that explanation out of the way, let's continue. Next, we take the number 30,503 and divide it by 2:
30,503 ÷ 2 = 15,251.5
If the quotient is a whole number, then 2 and 15,251.5 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 | 30,503 | |
-1 | -30,503 |
Now, we try dividing 30,503 by 3:
30,503 ÷ 3 = 10,167.6667
If the quotient is a whole number, then 3 and 10,167.6667 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 | 30,503 | |
-1 | -30,503 |
Let's try dividing by 4:
30,503 ÷ 4 = 7,625.75
If the quotient is a whole number, then 4 and 7,625.75 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 | 30,503 | |
-1 | 30,503 |
If you did it right, you will end up with this table:
1 | 11 | 47 | 59 | 517 | 649 | 2,773 | 30,503 |
-1 | -11 | -47 | -59 | -517 | -649 | -2,773 | -30,503 |
