How do I find the factor combinations of the number 920,949?
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 920,949, it is easier to work with a table - it's called factoring from the outside in.
Outside in Factoring
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.
Why are the negative numbers included?
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 920,949.
Example:
1 x 920,949 = 920,949
and
-1 x -920,949 = 920,949
Notice both answers equal 920,949
With that explanation out of the way, let's continue. Next, we take the number 920,949 and divide it by 2:
920,949 ÷ 2 = 460,474.5
If the quotient is a whole number, then 2 and 460,474.5 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:
Now, we try dividing 920,949 by 3:
920,949 ÷ 3 = 306,983
If the quotient is a whole number, then 3 and 306,983 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!
Here is what our table should look like at this step:
Let's try dividing by 4:
920,949 ÷ 4 = 230,237.25
If the quotient is a whole number, then 4 and 230,237.25 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:
Keep dividing by the next highest number until you cannot divide anymore.
If you did it right, you will end up with this table:
