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 20,002,433, 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 | 20,002,433 | |
| -1 | -20,002,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,002,433.
Example:
1 x 20,002,433 = 20,002,433
and
-1 x -20,002,433 = 20,002,433
Notice both answers equal 20,002,433
With that explanation out of the way, let's continue. Next, we take the number 20,002,433 and divide it by 2:
20,002,433 ÷ 2 = 10,001,216.5
If the quotient is a whole number, then 2 and 10,001,216.5 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 | 20,002,433 | |
| -1 | -20,002,433 |
Now, we try dividing 20,002,433 by 3:
20,002,433 ÷ 3 = 6,667,477.6667
If the quotient is a whole number, then 3 and 6,667,477.6667 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 | 20,002,433 | |
| -1 | -20,002,433 |
Let's try dividing by 4:
20,002,433 ÷ 4 = 5,000,608.25
If the quotient is a whole number, then 4 and 5,000,608.25 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 | 20,002,433 | |
| -1 | 20,002,433 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 173 | 253 | 457 | 1,903 | 3,979 | 5,027 | 10,511 | 43,769 | 79,061 | 115,621 | 869,671 | 1,818,403 | 20,002,433 |
| -1 | -11 | -23 | -173 | -253 | -457 | -1,903 | -3,979 | -5,027 | -10,511 | -43,769 | -79,061 | -115,621 | -869,671 | -1,818,403 | -20,002,433 |
