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 19,521,923, 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 | 19,521,923 | |
-1 | -19,521,923 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 19,521,923.
Example:
1 x 19,521,923 = 19,521,923
and
-1 x -19,521,923 = 19,521,923
Notice both answers equal 19,521,923
With that explanation out of the way, let's continue. Next, we take the number 19,521,923 and divide it by 2:
19,521,923 ÷ 2 = 9,760,961.5
If the quotient is a whole number, then 2 and 9,760,961.5 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 | 19,521,923 | |
-1 | -19,521,923 |
Now, we try dividing 19,521,923 by 3:
19,521,923 ÷ 3 = 6,507,307.6667
If the quotient is a whole number, then 3 and 6,507,307.6667 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 | 19,521,923 | |
-1 | -19,521,923 |
Let's try dividing by 4:
19,521,923 ÷ 4 = 4,880,480.75
If the quotient is a whole number, then 4 and 4,880,480.75 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 | 19,521,923 | |
-1 | 19,521,923 |
If you did it right, you will end up with this table:
1 | 863 | 22,621 | 19,521,923 |
-1 | -863 | -22,621 | -19,521,923 |
