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 789,065, 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 | 789,065 | |
-1 | -789,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 789,065.
Example:
1 x 789,065 = 789,065
and
-1 x -789,065 = 789,065
Notice both answers equal 789,065
With that explanation out of the way, let's continue. Next, we take the number 789,065 and divide it by 2:
789,065 ÷ 2 = 394,532.5
If the quotient is a whole number, then 2 and 394,532.5 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 | 789,065 | |
-1 | -789,065 |
Now, we try dividing 789,065 by 3:
789,065 ÷ 3 = 263,021.6667
If the quotient is a whole number, then 3 and 263,021.6667 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 | 789,065 | |
-1 | -789,065 |
Let's try dividing by 4:
789,065 ÷ 4 = 197,266.25
If the quotient is a whole number, then 4 and 197,266.25 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:
1 | 789,065 | |
-1 | 789,065 |
If you did it right, you will end up with this table:
1 | 5 | 157,813 | 789,065 |
-1 | -5 | -157,813 | -789,065 |
