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 12,224,225, 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 | 12,224,225 | |
| -1 | -12,224,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,224,225.
Example:
1 x 12,224,225 = 12,224,225
and
-1 x -12,224,225 = 12,224,225
Notice both answers equal 12,224,225
With that explanation out of the way, let's continue. Next, we take the number 12,224,225 and divide it by 2:
12,224,225 ÷ 2 = 6,112,112.5
If the quotient is a whole number, then 2 and 6,112,112.5 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 | 12,224,225 | |
| -1 | -12,224,225 |
Now, we try dividing 12,224,225 by 3:
12,224,225 ÷ 3 = 4,074,741.6667
If the quotient is a whole number, then 3 and 4,074,741.6667 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 | 12,224,225 | |
| -1 | -12,224,225 |
Let's try dividing by 4:
12,224,225 ÷ 4 = 3,056,056.25
If the quotient is a whole number, then 4 and 3,056,056.25 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 | 12,224,225 | |
| -1 | 12,224,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 29 | 65 | 145 | 325 | 377 | 725 | 1,297 | 1,885 | 6,485 | 9,425 | 16,861 | 32,425 | 37,613 | 84,305 | 188,065 | 421,525 | 488,969 | 940,325 | 2,444,845 | 12,224,225 |
| -1 | -5 | -13 | -25 | -29 | -65 | -145 | -325 | -377 | -725 | -1,297 | -1,885 | -6,485 | -9,425 | -16,861 | -32,425 | -37,613 | -84,305 | -188,065 | -421,525 | -488,969 | -940,325 | -2,444,845 | -12,224,225 |
