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 20,213,303, 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 | 20,213,303 | |
-1 | -20,213,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,213,303.
Example:
1 x 20,213,303 = 20,213,303
and
-1 x -20,213,303 = 20,213,303
Notice both answers equal 20,213,303
With that explanation out of the way, let's continue. Next, we take the number 20,213,303 and divide it by 2:
20,213,303 ÷ 2 = 10,106,651.5
If the quotient is a whole number, then 2 and 10,106,651.5 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 | 20,213,303 | |
-1 | -20,213,303 |
Now, we try dividing 20,213,303 by 3:
20,213,303 ÷ 3 = 6,737,767.6667
If the quotient is a whole number, then 3 and 6,737,767.6667 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 | 20,213,303 | |
-1 | -20,213,303 |
Let's try dividing by 4:
20,213,303 ÷ 4 = 5,053,325.75
If the quotient is a whole number, then 4 and 5,053,325.75 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 | 20,213,303 | |
-1 | 20,213,303 |
If you did it right, you will end up with this table:
1 | 11 | 1,837,573 | 20,213,303 |
-1 | -11 | -1,837,573 | -20,213,303 |
