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 20,017,075, 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 | 20,017,075 | |
| -1 | -20,017,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 20,017,075.
Example:
1 x 20,017,075 = 20,017,075
and
-1 x -20,017,075 = 20,017,075
Notice both answers equal 20,017,075
With that explanation out of the way, let's continue. Next, we take the number 20,017,075 and divide it by 2:
20,017,075 ÷ 2 = 10,008,537.5
If the quotient is a whole number, then 2 and 10,008,537.5 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 | 20,017,075 | |
| -1 | -20,017,075 |
Now, we try dividing 20,017,075 by 3:
20,017,075 ÷ 3 = 6,672,358.3333
If the quotient is a whole number, then 3 and 6,672,358.3333 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 | 20,017,075 | |
| -1 | -20,017,075 |
Let's try dividing by 4:
20,017,075 ÷ 4 = 5,004,268.75
If the quotient is a whole number, then 4 and 5,004,268.75 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 | 20,017,075 | |
| -1 | 20,017,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 25 | 65 | 85 | 221 | 325 | 425 | 1,105 | 3,623 | 5,525 | 18,115 | 47,099 | 61,591 | 90,575 | 235,495 | 307,955 | 800,683 | 1,177,475 | 1,539,775 | 4,003,415 | 20,017,075 |
| -1 | -5 | -13 | -17 | -25 | -65 | -85 | -221 | -325 | -425 | -1,105 | -3,623 | -5,525 | -18,115 | -47,099 | -61,591 | -90,575 | -235,495 | -307,955 | -800,683 | -1,177,475 | -1,539,775 | -4,003,415 | -20,017,075 |
