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 18,709,075, 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 | 18,709,075 | |
| -1 | -18,709,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,709,075.
Example:
1 x 18,709,075 = 18,709,075
and
-1 x -18,709,075 = 18,709,075
Notice both answers equal 18,709,075
With that explanation out of the way, let's continue. Next, we take the number 18,709,075 and divide it by 2:
18,709,075 ÷ 2 = 9,354,537.5
If the quotient is a whole number, then 2 and 9,354,537.5 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 | 18,709,075 | |
| -1 | -18,709,075 |
Now, we try dividing 18,709,075 by 3:
18,709,075 ÷ 3 = 6,236,358.3333
If the quotient is a whole number, then 3 and 6,236,358.3333 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 | 18,709,075 | |
| -1 | -18,709,075 |
Let's try dividing by 4:
18,709,075 ÷ 4 = 4,677,268.75
If the quotient is a whole number, then 4 and 4,677,268.75 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 | 18,709,075 | |
| -1 | 18,709,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 1,925 | 9,719 | 48,595 | 68,033 | 106,909 | 242,975 | 340,165 | 534,545 | 748,363 | 1,700,825 | 2,672,725 | 3,741,815 | 18,709,075 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -1,925 | -9,719 | -48,595 | -68,033 | -106,909 | -242,975 | -340,165 | -534,545 | -748,363 | -1,700,825 | -2,672,725 | -3,741,815 | -18,709,075 |
