A:
Positive:
1 x 416655 x 833313 x 320565 x 641
Negative:
-1 x -41665-5 x -8333-13 x -3205-65 x -641
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 41,665, 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 | 41,665 | |
-1 | -41,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,665.
Example:
1 x 41,665 = 41,665
and
-1 x -41,665 = 41,665
Notice both answers equal 41,665
With that explanation out of the way, let's continue. Next, we take the number 41,665 and divide it by 2:
41,665 ÷ 2 = 20,832.5
If the quotient is a whole number, then 2 and 20,832.5 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 | 41,665 | |
-1 | -41,665 |
Now, we try dividing 41,665 by 3:
41,665 ÷ 3 = 13,888.3333
If the quotient is a whole number, then 3 and 13,888.3333 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 | 41,665 | |
-1 | -41,665 |
Let's try dividing by 4:
41,665 ÷ 4 = 10,416.25
If the quotient is a whole number, then 4 and 10,416.25 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 | 41,665 | |
-1 | 41,665 |
If you did it right, you will end up with this table:
1 | 5 | 13 | 65 | 641 | 3,205 | 8,333 | 41,665 |
-1 | -5 | -13 | -65 | -641 | -3,205 | -8,333 | -41,665 |
