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 80,324,455, 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 | 80,324,455 | |
| -1 | -80,324,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 80,324,455.
Example:
1 x 80,324,455 = 80,324,455
and
-1 x -80,324,455 = 80,324,455
Notice both answers equal 80,324,455
With that explanation out of the way, let's continue. Next, we take the number 80,324,455 and divide it by 2:
80,324,455 ÷ 2 = 40,162,227.5
If the quotient is a whole number, then 2 and 40,162,227.5 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 | 80,324,455 | |
| -1 | -80,324,455 |
Now, we try dividing 80,324,455 by 3:
80,324,455 ÷ 3 = 26,774,818.3333
If the quotient is a whole number, then 3 and 26,774,818.3333 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 | 80,324,455 | |
| -1 | -80,324,455 |
Let's try dividing by 4:
80,324,455 ÷ 4 = 20,081,113.75
If the quotient is a whole number, then 4 and 20,081,113.75 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 | 80,324,455 | |
| -1 | 80,324,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 73 | 359 | 365 | 613 | 1,795 | 3,065 | 26,207 | 44,749 | 131,035 | 220,067 | 223,745 | 1,100,335 | 16,064,891 | 80,324,455 |
| -1 | -5 | -73 | -359 | -365 | -613 | -1,795 | -3,065 | -26,207 | -44,749 | -131,035 | -220,067 | -223,745 | -1,100,335 | -16,064,891 | -80,324,455 |
