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 23,925,503, 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 | 23,925,503 | |
| -1 | -23,925,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,925,503.
Example:
1 x 23,925,503 = 23,925,503
and
-1 x -23,925,503 = 23,925,503
Notice both answers equal 23,925,503
With that explanation out of the way, let's continue. Next, we take the number 23,925,503 and divide it by 2:
23,925,503 ÷ 2 = 11,962,751.5
If the quotient is a whole number, then 2 and 11,962,751.5 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 | 23,925,503 | |
| -1 | -23,925,503 |
Now, we try dividing 23,925,503 by 3:
23,925,503 ÷ 3 = 7,975,167.6667
If the quotient is a whole number, then 3 and 7,975,167.6667 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 | 23,925,503 | |
| -1 | -23,925,503 |
Let's try dividing by 4:
23,925,503 ÷ 4 = 5,981,375.75
If the quotient is a whole number, then 4 and 5,981,375.75 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 | 23,925,503 | |
| -1 | 23,925,503 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 59 | 133 | 413 | 1,121 | 3,049 | 7,847 | 21,343 | 57,931 | 179,891 | 405,517 | 1,259,237 | 3,417,929 | 23,925,503 |
| -1 | -7 | -19 | -59 | -133 | -413 | -1,121 | -3,049 | -7,847 | -21,343 | -57,931 | -179,891 | -405,517 | -1,259,237 | -3,417,929 | -23,925,503 |
