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 80,020,559, 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 | 80,020,559 | |
-1 | -80,020,559 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 80,020,559.
Example:
1 x 80,020,559 = 80,020,559
and
-1 x -80,020,559 = 80,020,559
Notice both answers equal 80,020,559
With that explanation out of the way, let's continue. Next, we take the number 80,020,559 and divide it by 2:
80,020,559 ÷ 2 = 40,010,279.5
If the quotient is a whole number, then 2 and 40,010,279.5 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 | 80,020,559 | |
-1 | -80,020,559 |
Now, we try dividing 80,020,559 by 3:
80,020,559 ÷ 3 = 26,673,519.6667
If the quotient is a whole number, then 3 and 26,673,519.6667 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 | 80,020,559 | |
-1 | -80,020,559 |
Let's try dividing by 4:
80,020,559 ÷ 4 = 20,005,139.75
If the quotient is a whole number, then 4 and 20,005,139.75 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 | 80,020,559 | |
-1 | 80,020,559 |
If you did it right, you will end up with this table:
1 | 811 | 98,669 | 80,020,559 |
-1 | -811 | -98,669 | -80,020,559 |
