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 18,123,011, 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 | 18,123,011 | |
-1 | -18,123,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,123,011.
Example:
1 x 18,123,011 = 18,123,011
and
-1 x -18,123,011 = 18,123,011
Notice both answers equal 18,123,011
With that explanation out of the way, let's continue. Next, we take the number 18,123,011 and divide it by 2:
18,123,011 ÷ 2 = 9,061,505.5
If the quotient is a whole number, then 2 and 9,061,505.5 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 | 18,123,011 | |
-1 | -18,123,011 |
Now, we try dividing 18,123,011 by 3:
18,123,011 ÷ 3 = 6,041,003.6667
If the quotient is a whole number, then 3 and 6,041,003.6667 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 | 18,123,011 | |
-1 | -18,123,011 |
Let's try dividing by 4:
18,123,011 ÷ 4 = 4,530,752.75
If the quotient is a whole number, then 4 and 4,530,752.75 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 | 18,123,011 | |
-1 | 18,123,011 |
If you did it right, you will end up with this table:
1 | 23 | 529 | 34,259 | 787,957 | 18,123,011 |
-1 | -23 | -529 | -34,259 | -787,957 | -18,123,011 |
