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 20,553,835, 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 | 20,553,835 | |
| -1 | -20,553,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,553,835.
Example:
1 x 20,553,835 = 20,553,835
and
-1 x -20,553,835 = 20,553,835
Notice both answers equal 20,553,835
With that explanation out of the way, let's continue. Next, we take the number 20,553,835 and divide it by 2:
20,553,835 ÷ 2 = 10,276,917.5
If the quotient is a whole number, then 2 and 10,276,917.5 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 | 20,553,835 | |
| -1 | -20,553,835 |
Now, we try dividing 20,553,835 by 3:
20,553,835 ÷ 3 = 6,851,278.3333
If the quotient is a whole number, then 3 and 6,851,278.3333 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 | 20,553,835 | |
| -1 | -20,553,835 |
Let's try dividing by 4:
20,553,835 ÷ 4 = 5,138,458.75
If the quotient is a whole number, then 4 and 5,138,458.75 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 | 20,553,835 | |
| -1 | 20,553,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 367 | 487 | 1,835 | 2,435 | 8,441 | 11,201 | 42,205 | 56,005 | 178,729 | 893,645 | 4,110,767 | 20,553,835 |
| -1 | -5 | -23 | -115 | -367 | -487 | -1,835 | -2,435 | -8,441 | -11,201 | -42,205 | -56,005 | -178,729 | -893,645 | -4,110,767 | -20,553,835 |
