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 80,324,447, 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 | 80,324,447 | |
| -1 | -80,324,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 80,324,447.
Example:
1 x 80,324,447 = 80,324,447
and
-1 x -80,324,447 = 80,324,447
Notice both answers equal 80,324,447
With that explanation out of the way, let's continue. Next, we take the number 80,324,447 and divide it by 2:
80,324,447 ÷ 2 = 40,162,223.5
If the quotient is a whole number, then 2 and 40,162,223.5 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 | 80,324,447 | |
| -1 | -80,324,447 |
Now, we try dividing 80,324,447 by 3:
80,324,447 ÷ 3 = 26,774,815.6667
If the quotient is a whole number, then 3 and 26,774,815.6667 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 | 80,324,447 | |
| -1 | -80,324,447 |
Let's try dividing by 4:
80,324,447 ÷ 4 = 20,081,111.75
If the quotient is a whole number, then 4 and 20,081,111.75 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 | 80,324,447 | |
| -1 | 80,324,447 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 103 | 259 | 721 | 3,011 | 3,811 | 21,077 | 26,677 | 111,407 | 310,133 | 779,849 | 2,170,931 | 11,474,921 | 80,324,447 |
| -1 | -7 | -37 | -103 | -259 | -721 | -3,011 | -3,811 | -21,077 | -26,677 | -111,407 | -310,133 | -779,849 | -2,170,931 | -11,474,921 | -80,324,447 |
