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 82,560,217, 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 | 82,560,217 | |
-1 | -82,560,217 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,560,217.
Example:
1 x 82,560,217 = 82,560,217
and
-1 x -82,560,217 = 82,560,217
Notice both answers equal 82,560,217
With that explanation out of the way, let's continue. Next, we take the number 82,560,217 and divide it by 2:
82,560,217 ÷ 2 = 41,280,108.5
If the quotient is a whole number, then 2 and 41,280,108.5 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 | 82,560,217 | |
-1 | -82,560,217 |
Now, we try dividing 82,560,217 by 3:
82,560,217 ÷ 3 = 27,520,072.3333
If the quotient is a whole number, then 3 and 27,520,072.3333 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 | 82,560,217 | |
-1 | -82,560,217 |
Let's try dividing by 4:
82,560,217 ÷ 4 = 20,640,054.25
If the quotient is a whole number, then 4 and 20,640,054.25 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 | 82,560,217 | |
-1 | 82,560,217 |
If you did it right, you will end up with this table:
1 | 3,433 | 24,049 | 82,560,217 |
-1 | -3,433 | -24,049 | -82,560,217 |
