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 82,777, 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 | 82,777 | |
-1 | -82,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,777.
Example:
1 x 82,777 = 82,777
and
-1 x -82,777 = 82,777
Notice both answers equal 82,777
With that explanation out of the way, let's continue. Next, we take the number 82,777 and divide it by 2:
82,777 ÷ 2 = 41,388.5
If the quotient is a whole number, then 2 and 41,388.5 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 | 82,777 | |
-1 | -82,777 |
Now, we try dividing 82,777 by 3:
82,777 ÷ 3 = 27,592.3333
If the quotient is a whole number, then 3 and 27,592.3333 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 | 82,777 | |
-1 | -82,777 |
Let's try dividing by 4:
82,777 ÷ 4 = 20,694.25
If the quotient is a whole number, then 4 and 20,694.25 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 | 82,777 | |
-1 | 82,777 |
If you did it right, you will end up with this table:
1 | 23 | 59 | 61 | 1,357 | 1,403 | 3,599 | 82,777 |
-1 | -23 | -59 | -61 | -1,357 | -1,403 | -3,599 | -82,777 |
