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 197,783, 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 | 197,783 | |
-1 | -197,783 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 197,783.
Example:
1 x 197,783 = 197,783
and
-1 x -197,783 = 197,783
Notice both answers equal 197,783
With that explanation out of the way, let's continue. Next, we take the number 197,783 and divide it by 2:
197,783 ÷ 2 = 98,891.5
If the quotient is a whole number, then 2 and 98,891.5 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 | 197,783 | |
-1 | -197,783 |
Now, we try dividing 197,783 by 3:
197,783 ÷ 3 = 65,927.6667
If the quotient is a whole number, then 3 and 65,927.6667 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 | 197,783 | |
-1 | -197,783 |
Let's try dividing by 4:
197,783 ÷ 4 = 49,445.75
If the quotient is a whole number, then 4 and 49,445.75 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 | 197,783 | |
-1 | 197,783 |
If you did it right, you will end up with this table:
1 | 97 | 2,039 | 197,783 |
-1 | -97 | -2,039 | -197,783 |
