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 20,392,333, 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 | 20,392,333 | |
| -1 | -20,392,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,392,333.
Example:
1 x 20,392,333 = 20,392,333
and
-1 x -20,392,333 = 20,392,333
Notice both answers equal 20,392,333
With that explanation out of the way, let's continue. Next, we take the number 20,392,333 and divide it by 2:
20,392,333 ÷ 2 = 10,196,166.5
If the quotient is a whole number, then 2 and 10,196,166.5 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 | 20,392,333 | |
| -1 | -20,392,333 |
Now, we try dividing 20,392,333 by 3:
20,392,333 ÷ 3 = 6,797,444.3333
If the quotient is a whole number, then 3 and 6,797,444.3333 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 | 20,392,333 | |
| -1 | -20,392,333 |
Let's try dividing by 4:
20,392,333 ÷ 4 = 5,098,083.25
If the quotient is a whole number, then 4 and 5,098,083.25 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 | 20,392,333 | |
| -1 | 20,392,333 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 53 | 221 | 689 | 901 | 1,741 | 11,713 | 22,633 | 29,597 | 92,273 | 384,761 | 1,199,549 | 1,568,641 | 20,392,333 |
| -1 | -13 | -17 | -53 | -221 | -689 | -901 | -1,741 | -11,713 | -22,633 | -29,597 | -92,273 | -384,761 | -1,199,549 | -1,568,641 | -20,392,333 |
