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 863,039, 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 | 863,039 | |
-1 | -863,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 863,039.
Example:
1 x 863,039 = 863,039
and
-1 x -863,039 = 863,039
Notice both answers equal 863,039
With that explanation out of the way, let's continue. Next, we take the number 863,039 and divide it by 2:
863,039 ÷ 2 = 431,519.5
If the quotient is a whole number, then 2 and 431,519.5 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 | 863,039 | |
-1 | -863,039 |
Now, we try dividing 863,039 by 3:
863,039 ÷ 3 = 287,679.6667
If the quotient is a whole number, then 3 and 287,679.6667 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 | 863,039 | |
-1 | -863,039 |
Let's try dividing by 4:
863,039 ÷ 4 = 215,759.75
If the quotient is a whole number, then 4 and 215,759.75 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 | 863,039 | |
-1 | 863,039 |
If you did it right, you will end up with this table:
1 | 17 | 50,767 | 863,039 |
-1 | -17 | -50,767 | -863,039 |
