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 20,005,535, 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 | 20,005,535 | |
| -1 | -20,005,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,005,535.
Example:
1 x 20,005,535 = 20,005,535
and
-1 x -20,005,535 = 20,005,535
Notice both answers equal 20,005,535
With that explanation out of the way, let's continue. Next, we take the number 20,005,535 and divide it by 2:
20,005,535 ÷ 2 = 10,002,767.5
If the quotient is a whole number, then 2 and 10,002,767.5 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 | 20,005,535 | |
| -1 | -20,005,535 |
Now, we try dividing 20,005,535 by 3:
20,005,535 ÷ 3 = 6,668,511.6667
If the quotient is a whole number, then 3 and 6,668,511.6667 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 | 20,005,535 | |
| -1 | -20,005,535 |
Let's try dividing by 4:
20,005,535 ÷ 4 = 5,001,383.75
If the quotient is a whole number, then 4 and 5,001,383.75 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 | 20,005,535 | |
| -1 | 20,005,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 43 | 55 | 121 | 215 | 473 | 605 | 769 | 2,365 | 3,845 | 5,203 | 8,459 | 26,015 | 33,067 | 42,295 | 93,049 | 165,335 | 363,737 | 465,245 | 1,818,685 | 4,001,107 | 20,005,535 |
| -1 | -5 | -11 | -43 | -55 | -121 | -215 | -473 | -605 | -769 | -2,365 | -3,845 | -5,203 | -8,459 | -26,015 | -33,067 | -42,295 | -93,049 | -165,335 | -363,737 | -465,245 | -1,818,685 | -4,001,107 | -20,005,535 |
