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 21,635,033, 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 | 21,635,033 | |
| -1 | -21,635,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 21,635,033.
Example:
1 x 21,635,033 = 21,635,033
and
-1 x -21,635,033 = 21,635,033
Notice both answers equal 21,635,033
With that explanation out of the way, let's continue. Next, we take the number 21,635,033 and divide it by 2:
21,635,033 ÷ 2 = 10,817,516.5
If the quotient is a whole number, then 2 and 10,817,516.5 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 | 21,635,033 | |
| -1 | -21,635,033 |
Now, we try dividing 21,635,033 by 3:
21,635,033 ÷ 3 = 7,211,677.6667
If the quotient is a whole number, then 3 and 7,211,677.6667 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 | 21,635,033 | |
| -1 | -21,635,033 |
Let's try dividing by 4:
21,635,033 ÷ 4 = 5,408,758.25
If the quotient is a whole number, then 4 and 5,408,758.25 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 | 21,635,033 | |
| -1 | 21,635,033 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 281 | 647 | 1,967 | 4,529 | 4,777 | 10,999 | 33,439 | 76,993 | 181,807 | 1,272,649 | 3,090,719 | 21,635,033 |
| -1 | -7 | -17 | -119 | -281 | -647 | -1,967 | -4,529 | -4,777 | -10,999 | -33,439 | -76,993 | -181,807 | -1,272,649 | -3,090,719 | -21,635,033 |
