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 12,022,225, 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 | 12,022,225 | |
| -1 | -12,022,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,022,225.
Example:
1 x 12,022,225 = 12,022,225
and
-1 x -12,022,225 = 12,022,225
Notice both answers equal 12,022,225
With that explanation out of the way, let's continue. Next, we take the number 12,022,225 and divide it by 2:
12,022,225 ÷ 2 = 6,011,112.5
If the quotient is a whole number, then 2 and 6,011,112.5 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 | 12,022,225 | |
| -1 | -12,022,225 |
Now, we try dividing 12,022,225 by 3:
12,022,225 ÷ 3 = 4,007,408.3333
If the quotient is a whole number, then 3 and 4,007,408.3333 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 | 12,022,225 | |
| -1 | -12,022,225 |
Let's try dividing by 4:
12,022,225 ÷ 4 = 3,005,556.25
If the quotient is a whole number, then 4 and 3,005,556.25 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 | 12,022,225 | |
| -1 | 12,022,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 37 | 41 | 185 | 205 | 317 | 925 | 1,025 | 1,517 | 1,585 | 7,585 | 7,925 | 11,729 | 12,997 | 37,925 | 58,645 | 64,985 | 293,225 | 324,925 | 480,889 | 2,404,445 | 12,022,225 |
| -1 | -5 | -25 | -37 | -41 | -185 | -205 | -317 | -925 | -1,025 | -1,517 | -1,585 | -7,585 | -7,925 | -11,729 | -12,997 | -37,925 | -58,645 | -64,985 | -293,225 | -324,925 | -480,889 | -2,404,445 | -12,022,225 |
