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 82,662,551, 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 | 82,662,551 | |
| -1 | -82,662,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,662,551.
Example:
1 x 82,662,551 = 82,662,551
and
-1 x -82,662,551 = 82,662,551
Notice both answers equal 82,662,551
With that explanation out of the way, let's continue. Next, we take the number 82,662,551 and divide it by 2:
82,662,551 ÷ 2 = 41,331,275.5
If the quotient is a whole number, then 2 and 41,331,275.5 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 | 82,662,551 | |
| -1 | -82,662,551 |
Now, we try dividing 82,662,551 by 3:
82,662,551 ÷ 3 = 27,554,183.6667
If the quotient is a whole number, then 3 and 27,554,183.6667 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 | 82,662,551 | |
| -1 | -82,662,551 |
Let's try dividing by 4:
82,662,551 ÷ 4 = 20,665,637.75
If the quotient is a whole number, then 4 and 20,665,637.75 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 | 82,662,551 | |
| -1 | 82,662,551 |
If you did it right, you will end up with this table:
| 1 | 17 | 37 | 113 | 629 | 1,163 | 1,921 | 4,181 | 19,771 | 43,031 | 71,077 | 131,419 | 731,527 | 2,234,123 | 4,862,503 | 82,662,551 |
| -1 | -17 | -37 | -113 | -629 | -1,163 | -1,921 | -4,181 | -19,771 | -43,031 | -71,077 | -131,419 | -731,527 | -2,234,123 | -4,862,503 | -82,662,551 |
