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 20,441,125, 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 | 20,441,125 | |
| -1 | -20,441,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,441,125.
Example:
1 x 20,441,125 = 20,441,125
and
-1 x -20,441,125 = 20,441,125
Notice both answers equal 20,441,125
With that explanation out of the way, let's continue. Next, we take the number 20,441,125 and divide it by 2:
20,441,125 ÷ 2 = 10,220,562.5
If the quotient is a whole number, then 2 and 10,220,562.5 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 | 20,441,125 | |
| -1 | -20,441,125 |
Now, we try dividing 20,441,125 by 3:
20,441,125 ÷ 3 = 6,813,708.3333
If the quotient is a whole number, then 3 and 6,813,708.3333 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 | 20,441,125 | |
| -1 | -20,441,125 |
Let's try dividing by 4:
20,441,125 ÷ 4 = 5,110,281.25
If the quotient is a whole number, then 4 and 5,110,281.25 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 | 20,441,125 | |
| -1 | 20,441,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 125 | 215 | 1,075 | 3,803 | 5,375 | 19,015 | 95,075 | 163,529 | 475,375 | 817,645 | 4,088,225 | 20,441,125 |
| -1 | -5 | -25 | -43 | -125 | -215 | -1,075 | -3,803 | -5,375 | -19,015 | -95,075 | -163,529 | -475,375 | -817,645 | -4,088,225 | -20,441,125 |
