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 81,010,333, 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 | 81,010,333 | |
-1 | -81,010,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 81,010,333.
Example:
1 x 81,010,333 = 81,010,333
and
-1 x -81,010,333 = 81,010,333
Notice both answers equal 81,010,333
With that explanation out of the way, let's continue. Next, we take the number 81,010,333 and divide it by 2:
81,010,333 ÷ 2 = 40,505,166.5
If the quotient is a whole number, then 2 and 40,505,166.5 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 | 81,010,333 | |
-1 | -81,010,333 |
Now, we try dividing 81,010,333 by 3:
81,010,333 ÷ 3 = 27,003,444.3333
If the quotient is a whole number, then 3 and 27,003,444.3333 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 | 81,010,333 | |
-1 | -81,010,333 |
Let's try dividing by 4:
81,010,333 ÷ 4 = 20,252,583.25
If the quotient is a whole number, then 4 and 20,252,583.25 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 | 81,010,333 | |
-1 | 81,010,333 |
If you did it right, you will end up with this table:
1 | 281 | 288,293 | 81,010,333 |
-1 | -281 | -288,293 | -81,010,333 |
