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 23,318,021, 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 | 23,318,021 | |
-1 | -23,318,021 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,318,021.
Example:
1 x 23,318,021 = 23,318,021
and
-1 x -23,318,021 = 23,318,021
Notice both answers equal 23,318,021
With that explanation out of the way, let's continue. Next, we take the number 23,318,021 and divide it by 2:
23,318,021 ÷ 2 = 11,659,010.5
If the quotient is a whole number, then 2 and 11,659,010.5 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 | 23,318,021 | |
-1 | -23,318,021 |
Now, we try dividing 23,318,021 by 3:
23,318,021 ÷ 3 = 7,772,673.6667
If the quotient is a whole number, then 3 and 7,772,673.6667 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 | 23,318,021 | |
-1 | -23,318,021 |
Let's try dividing by 4:
23,318,021 ÷ 4 = 5,829,505.25
If the quotient is a whole number, then 4 and 5,829,505.25 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 | 23,318,021 | |
-1 | 23,318,021 |
If you did it right, you will end up with this table:
1 | 23 | 1,013,827 | 23,318,021 |
-1 | -23 | -1,013,827 | -23,318,021 |
