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 20,756,495, 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 | 20,756,495 | |
| -1 | -20,756,495 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,756,495.
Example:
1 x 20,756,495 = 20,756,495
and
-1 x -20,756,495 = 20,756,495
Notice both answers equal 20,756,495
With that explanation out of the way, let's continue. Next, we take the number 20,756,495 and divide it by 2:
20,756,495 ÷ 2 = 10,378,247.5
If the quotient is a whole number, then 2 and 10,378,247.5 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 | 20,756,495 | |
| -1 | -20,756,495 |
Now, we try dividing 20,756,495 by 3:
20,756,495 ÷ 3 = 6,918,831.6667
If the quotient is a whole number, then 3 and 6,918,831.6667 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 | 20,756,495 | |
| -1 | -20,756,495 |
Let's try dividing by 4:
20,756,495 ÷ 4 = 5,189,123.75
If the quotient is a whole number, then 4 and 5,189,123.75 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 | 20,756,495 | |
| -1 | 20,756,495 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 71 | 295 | 355 | 991 | 4,189 | 4,955 | 20,945 | 58,469 | 70,361 | 292,345 | 351,805 | 4,151,299 | 20,756,495 |
| -1 | -5 | -59 | -71 | -295 | -355 | -991 | -4,189 | -4,955 | -20,945 | -58,469 | -70,361 | -292,345 | -351,805 | -4,151,299 | -20,756,495 |
