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 20,334,433, 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 | 20,334,433 | |
| -1 | -20,334,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,334,433.
Example:
1 x 20,334,433 = 20,334,433
and
-1 x -20,334,433 = 20,334,433
Notice both answers equal 20,334,433
With that explanation out of the way, let's continue. Next, we take the number 20,334,433 and divide it by 2:
20,334,433 ÷ 2 = 10,167,216.5
If the quotient is a whole number, then 2 and 10,167,216.5 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 | 20,334,433 | |
| -1 | -20,334,433 |
Now, we try dividing 20,334,433 by 3:
20,334,433 ÷ 3 = 6,778,144.3333
If the quotient is a whole number, then 3 and 6,778,144.3333 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 | 20,334,433 | |
| -1 | -20,334,433 |
Let's try dividing by 4:
20,334,433 ÷ 4 = 5,083,608.25
If the quotient is a whole number, then 4 and 5,083,608.25 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 | 20,334,433 | |
| -1 | 20,334,433 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 191 | 227 | 469 | 1,337 | 1,589 | 12,797 | 15,209 | 43,357 | 89,579 | 106,463 | 303,499 | 2,904,919 | 20,334,433 |
| -1 | -7 | -67 | -191 | -227 | -469 | -1,337 | -1,589 | -12,797 | -15,209 | -43,357 | -89,579 | -106,463 | -303,499 | -2,904,919 | -20,334,433 |
