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 18,459,625, 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 | 18,459,625 | |
| -1 | -18,459,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,459,625.
Example:
1 x 18,459,625 = 18,459,625
and
-1 x -18,459,625 = 18,459,625
Notice both answers equal 18,459,625
With that explanation out of the way, let's continue. Next, we take the number 18,459,625 and divide it by 2:
18,459,625 ÷ 2 = 9,229,812.5
If the quotient is a whole number, then 2 and 9,229,812.5 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 | 18,459,625 | |
| -1 | -18,459,625 |
Now, we try dividing 18,459,625 by 3:
18,459,625 ÷ 3 = 6,153,208.3333
If the quotient is a whole number, then 3 and 6,153,208.3333 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 | 18,459,625 | |
| -1 | -18,459,625 |
Let's try dividing by 4:
18,459,625 ÷ 4 = 4,614,906.25
If the quotient is a whole number, then 4 and 4,614,906.25 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 | 18,459,625 | |
| -1 | 18,459,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 59 | 125 | 295 | 1,475 | 2,503 | 7,375 | 12,515 | 62,575 | 147,677 | 312,875 | 738,385 | 3,691,925 | 18,459,625 |
| -1 | -5 | -25 | -59 | -125 | -295 | -1,475 | -2,503 | -7,375 | -12,515 | -62,575 | -147,677 | -312,875 | -738,385 | -3,691,925 | -18,459,625 |
