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 82,195,531, 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 | 82,195,531 | |
-1 | -82,195,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,195,531.
Example:
1 x 82,195,531 = 82,195,531
and
-1 x -82,195,531 = 82,195,531
Notice both answers equal 82,195,531
With that explanation out of the way, let's continue. Next, we take the number 82,195,531 and divide it by 2:
82,195,531 ÷ 2 = 41,097,765.5
If the quotient is a whole number, then 2 and 41,097,765.5 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 | 82,195,531 | |
-1 | -82,195,531 |
Now, we try dividing 82,195,531 by 3:
82,195,531 ÷ 3 = 27,398,510.3333
If the quotient is a whole number, then 3 and 27,398,510.3333 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 | 82,195,531 | |
-1 | -82,195,531 |
Let's try dividing by 4:
82,195,531 ÷ 4 = 20,548,882.75
If the quotient is a whole number, then 4 and 20,548,882.75 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 | 82,195,531 | |
-1 | 82,195,531 |
If you did it right, you will end up with this table:
1 | 11 | 7,472,321 | 82,195,531 |
-1 | -11 | -7,472,321 | -82,195,531 |
