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 20,803,771, 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 | 20,803,771 | |
-1 | -20,803,771 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,803,771.
Example:
1 x 20,803,771 = 20,803,771
and
-1 x -20,803,771 = 20,803,771
Notice both answers equal 20,803,771
With that explanation out of the way, let's continue. Next, we take the number 20,803,771 and divide it by 2:
20,803,771 ÷ 2 = 10,401,885.5
If the quotient is a whole number, then 2 and 10,401,885.5 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 | 20,803,771 | |
-1 | -20,803,771 |
Now, we try dividing 20,803,771 by 3:
20,803,771 ÷ 3 = 6,934,590.3333
If the quotient is a whole number, then 3 and 6,934,590.3333 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 | 20,803,771 | |
-1 | -20,803,771 |
Let's try dividing by 4:
20,803,771 ÷ 4 = 5,200,942.75
If the quotient is a whole number, then 4 and 5,200,942.75 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 | 20,803,771 | |
-1 | 20,803,771 |
If you did it right, you will end up with this table:
1 | 439 | 47,389 | 20,803,771 |
-1 | -439 | -47,389 | -20,803,771 |
