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 11,302,225, 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 | 11,302,225 | |
| -1 | -11,302,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,302,225.
Example:
1 x 11,302,225 = 11,302,225
and
-1 x -11,302,225 = 11,302,225
Notice both answers equal 11,302,225
With that explanation out of the way, let's continue. Next, we take the number 11,302,225 and divide it by 2:
11,302,225 ÷ 2 = 5,651,112.5
If the quotient is a whole number, then 2 and 5,651,112.5 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 | 11,302,225 | |
| -1 | -11,302,225 |
Now, we try dividing 11,302,225 by 3:
11,302,225 ÷ 3 = 3,767,408.3333
If the quotient is a whole number, then 3 and 3,767,408.3333 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 | 11,302,225 | |
| -1 | -11,302,225 |
Let's try dividing by 4:
11,302,225 ÷ 4 = 2,825,556.25
If the quotient is a whole number, then 4 and 2,825,556.25 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 | 11,302,225 | |
| -1 | 11,302,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 73 | 275 | 365 | 563 | 803 | 1,825 | 2,815 | 4,015 | 6,193 | 14,075 | 20,075 | 30,965 | 41,099 | 154,825 | 205,495 | 452,089 | 1,027,475 | 2,260,445 | 11,302,225 |
| -1 | -5 | -11 | -25 | -55 | -73 | -275 | -365 | -563 | -803 | -1,825 | -2,815 | -4,015 | -6,193 | -14,075 | -20,075 | -30,965 | -41,099 | -154,825 | -205,495 | -452,089 | -1,027,475 | -2,260,445 | -11,302,225 |
