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 11,202,125, 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 | 11,202,125 | |
| -1 | -11,202,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,202,125.
Example:
1 x 11,202,125 = 11,202,125
and
-1 x -11,202,125 = 11,202,125
Notice both answers equal 11,202,125
With that explanation out of the way, let's continue. Next, we take the number 11,202,125 and divide it by 2:
11,202,125 ÷ 2 = 5,601,062.5
If the quotient is a whole number, then 2 and 5,601,062.5 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 | 11,202,125 | |
| -1 | -11,202,125 |
Now, we try dividing 11,202,125 by 3:
11,202,125 ÷ 3 = 3,734,041.6667
If the quotient is a whole number, then 3 and 3,734,041.6667 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 | 11,202,125 | |
| -1 | -11,202,125 |
Let's try dividing by 4:
11,202,125 ÷ 4 = 2,800,531.25
If the quotient is a whole number, then 4 and 2,800,531.25 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 | 11,202,125 | |
| -1 | 11,202,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 1,375 | 8,147 | 40,735 | 89,617 | 203,675 | 448,085 | 1,018,375 | 2,240,425 | 11,202,125 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -1,375 | -8,147 | -40,735 | -89,617 | -203,675 | -448,085 | -1,018,375 | -2,240,425 | -11,202,125 |
