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 23,320,225, 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 | 23,320,225 | |
| -1 | -23,320,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,320,225.
Example:
1 x 23,320,225 = 23,320,225
and
-1 x -23,320,225 = 23,320,225
Notice both answers equal 23,320,225
With that explanation out of the way, let's continue. Next, we take the number 23,320,225 and divide it by 2:
23,320,225 ÷ 2 = 11,660,112.5
If the quotient is a whole number, then 2 and 11,660,112.5 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 | 23,320,225 | |
| -1 | -23,320,225 |
Now, we try dividing 23,320,225 by 3:
23,320,225 ÷ 3 = 7,773,408.3333
If the quotient is a whole number, then 3 and 7,773,408.3333 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 | 23,320,225 | |
| -1 | -23,320,225 |
Let's try dividing by 4:
23,320,225 ÷ 4 = 5,830,056.25
If the quotient is a whole number, then 4 and 5,830,056.25 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 | 23,320,225 | |
| -1 | 23,320,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 47 | 89 | 223 | 235 | 445 | 1,115 | 1,175 | 2,225 | 4,183 | 5,575 | 10,481 | 19,847 | 20,915 | 52,405 | 99,235 | 104,575 | 262,025 | 496,175 | 932,809 | 4,664,045 | 23,320,225 |
| -1 | -5 | -25 | -47 | -89 | -223 | -235 | -445 | -1,115 | -1,175 | -2,225 | -4,183 | -5,575 | -10,481 | -19,847 | -20,915 | -52,405 | -99,235 | -104,575 | -262,025 | -496,175 | -932,809 | -4,664,045 | -23,320,225 |
