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 18,085,625, 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 | 18,085,625 | |
| -1 | -18,085,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,085,625.
Example:
1 x 18,085,625 = 18,085,625
and
-1 x -18,085,625 = 18,085,625
Notice both answers equal 18,085,625
With that explanation out of the way, let's continue. Next, we take the number 18,085,625 and divide it by 2:
18,085,625 ÷ 2 = 9,042,812.5
If the quotient is a whole number, then 2 and 9,042,812.5 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 | 18,085,625 | |
| -1 | -18,085,625 |
Now, we try dividing 18,085,625 by 3:
18,085,625 ÷ 3 = 6,028,541.6667
If the quotient is a whole number, then 3 and 6,028,541.6667 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 | 18,085,625 | |
| -1 | -18,085,625 |
Let's try dividing by 4:
18,085,625 ÷ 4 = 4,521,406.25
If the quotient is a whole number, then 4 and 4,521,406.25 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 | 18,085,625 | |
| -1 | 18,085,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 125 | 475 | 625 | 1,523 | 2,375 | 7,615 | 11,875 | 28,937 | 38,075 | 144,685 | 190,375 | 723,425 | 951,875 | 3,617,125 | 18,085,625 |
| -1 | -5 | -19 | -25 | -95 | -125 | -475 | -625 | -1,523 | -2,375 | -7,615 | -11,875 | -28,937 | -38,075 | -144,685 | -190,375 | -723,425 | -951,875 | -3,617,125 | -18,085,625 |
