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 30,224,225, 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 | 30,224,225 | |
| -1 | -30,224,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,224,225.
Example:
1 x 30,224,225 = 30,224,225
and
-1 x -30,224,225 = 30,224,225
Notice both answers equal 30,224,225
With that explanation out of the way, let's continue. Next, we take the number 30,224,225 and divide it by 2:
30,224,225 ÷ 2 = 15,112,112.5
If the quotient is a whole number, then 2 and 15,112,112.5 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 | 30,224,225 | |
| -1 | -30,224,225 |
Now, we try dividing 30,224,225 by 3:
30,224,225 ÷ 3 = 10,074,741.6667
If the quotient is a whole number, then 3 and 10,074,741.6667 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 | 30,224,225 | |
| -1 | -30,224,225 |
Let's try dividing by 4:
30,224,225 ÷ 4 = 7,556,056.25
If the quotient is a whole number, then 4 and 7,556,056.25 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 | 30,224,225 | |
| -1 | 30,224,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 59 | 155 | 295 | 661 | 775 | 1,475 | 1,829 | 3,305 | 9,145 | 16,525 | 20,491 | 38,999 | 45,725 | 102,455 | 194,995 | 512,275 | 974,975 | 1,208,969 | 6,044,845 | 30,224,225 |
| -1 | -5 | -25 | -31 | -59 | -155 | -295 | -661 | -775 | -1,475 | -1,829 | -3,305 | -9,145 | -16,525 | -20,491 | -38,999 | -45,725 | -102,455 | -194,995 | -512,275 | -974,975 | -1,208,969 | -6,044,845 | -30,224,225 |
