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 203,071, 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 | 203,071 | |
-1 | -203,071 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,071.
Example:
1 x 203,071 = 203,071
and
-1 x -203,071 = 203,071
Notice both answers equal 203,071
With that explanation out of the way, let's continue. Next, we take the number 203,071 and divide it by 2:
203,071 ÷ 2 = 101,535.5
If the quotient is a whole number, then 2 and 101,535.5 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 | 203,071 | |
-1 | -203,071 |
Now, we try dividing 203,071 by 3:
203,071 ÷ 3 = 67,690.3333
If the quotient is a whole number, then 3 and 67,690.3333 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 | 203,071 | |
-1 | -203,071 |
Let's try dividing by 4:
203,071 ÷ 4 = 50,767.75
If the quotient is a whole number, then 4 and 50,767.75 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 | 203,071 | |
-1 | 203,071 |
If you did it right, you will end up with this table:
1 | 11 | 18,461 | 203,071 |
-1 | -11 | -18,461 | -203,071 |
