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 20,012,575, 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 | 20,012,575 | |
| -1 | -20,012,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,012,575.
Example:
1 x 20,012,575 = 20,012,575
and
-1 x -20,012,575 = 20,012,575
Notice both answers equal 20,012,575
With that explanation out of the way, let's continue. Next, we take the number 20,012,575 and divide it by 2:
20,012,575 ÷ 2 = 10,006,287.5
If the quotient is a whole number, then 2 and 10,006,287.5 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 | 20,012,575 | |
| -1 | -20,012,575 |
Now, we try dividing 20,012,575 by 3:
20,012,575 ÷ 3 = 6,670,858.3333
If the quotient is a whole number, then 3 and 6,670,858.3333 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 | 20,012,575 | |
| -1 | -20,012,575 |
Let's try dividing by 4:
20,012,575 ÷ 4 = 5,003,143.75
If the quotient is a whole number, then 4 and 5,003,143.75 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 | 20,012,575 | |
| -1 | 20,012,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 61 | 275 | 305 | 671 | 1,193 | 1,525 | 3,355 | 5,965 | 13,123 | 16,775 | 29,825 | 65,615 | 72,773 | 328,075 | 363,865 | 800,503 | 1,819,325 | 4,002,515 | 20,012,575 |
| -1 | -5 | -11 | -25 | -55 | -61 | -275 | -305 | -671 | -1,193 | -1,525 | -3,355 | -5,965 | -13,123 | -16,775 | -29,825 | -65,615 | -72,773 | -328,075 | -363,865 | -800,503 | -1,819,325 | -4,002,515 | -20,012,575 |
