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 80,579, 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 | 80,579 | |
-1 | -80,579 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 80,579.
Example:
1 x 80,579 = 80,579
and
-1 x -80,579 = 80,579
Notice both answers equal 80,579
With that explanation out of the way, let's continue. Next, we take the number 80,579 and divide it by 2:
80,579 ÷ 2 = 40,289.5
If the quotient is a whole number, then 2 and 40,289.5 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 | 80,579 | |
-1 | -80,579 |
Now, we try dividing 80,579 by 3:
80,579 ÷ 3 = 26,859.6667
If the quotient is a whole number, then 3 and 26,859.6667 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 | 80,579 | |
-1 | -80,579 |
Let's try dividing by 4:
80,579 ÷ 4 = 20,144.75
If the quotient is a whole number, then 4 and 20,144.75 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 | 80,579 | |
-1 | 80,579 |
If you did it right, you will end up with this table:
1 | 19 | 4,241 | 80,579 |
-1 | -19 | -4,241 | -80,579 |
