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 20,333,435, 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 | 20,333,435 | |
| -1 | -20,333,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,333,435.
Example:
1 x 20,333,435 = 20,333,435
and
-1 x -20,333,435 = 20,333,435
Notice both answers equal 20,333,435
With that explanation out of the way, let's continue. Next, we take the number 20,333,435 and divide it by 2:
20,333,435 ÷ 2 = 10,166,717.5
If the quotient is a whole number, then 2 and 10,166,717.5 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 | 20,333,435 | |
| -1 | -20,333,435 |
Now, we try dividing 20,333,435 by 3:
20,333,435 ÷ 3 = 6,777,811.6667
If the quotient is a whole number, then 3 and 6,777,811.6667 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 | 20,333,435 | |
| -1 | -20,333,435 |
Let's try dividing by 4:
20,333,435 ÷ 4 = 5,083,358.75
If the quotient is a whole number, then 4 and 5,083,358.75 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 | 20,333,435 | |
| -1 | 20,333,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 61 | 163 | 305 | 409 | 815 | 2,045 | 9,943 | 24,949 | 49,715 | 66,667 | 124,745 | 333,335 | 4,066,687 | 20,333,435 |
| -1 | -5 | -61 | -163 | -305 | -409 | -815 | -2,045 | -9,943 | -24,949 | -49,715 | -66,667 | -124,745 | -333,335 | -4,066,687 | -20,333,435 |
