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 11,151,455, 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 | 11,151,455 | |
| -1 | -11,151,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,151,455.
Example:
1 x 11,151,455 = 11,151,455
and
-1 x -11,151,455 = 11,151,455
Notice both answers equal 11,151,455
With that explanation out of the way, let's continue. Next, we take the number 11,151,455 and divide it by 2:
11,151,455 ÷ 2 = 5,575,727.5
If the quotient is a whole number, then 2 and 5,575,727.5 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 | 11,151,455 | |
| -1 | -11,151,455 |
Now, we try dividing 11,151,455 by 3:
11,151,455 ÷ 3 = 3,717,151.6667
If the quotient is a whole number, then 3 and 3,717,151.6667 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 | 11,151,455 | |
| -1 | -11,151,455 |
Let's try dividing by 4:
11,151,455 ÷ 4 = 2,787,863.75
If the quotient is a whole number, then 4 and 2,787,863.75 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 | 11,151,455 | |
| -1 | 11,151,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 235 | 329 | 1,645 | 6,779 | 33,895 | 47,453 | 237,265 | 318,613 | 1,593,065 | 2,230,291 | 11,151,455 |
| -1 | -5 | -7 | -35 | -47 | -235 | -329 | -1,645 | -6,779 | -33,895 | -47,453 | -237,265 | -318,613 | -1,593,065 | -2,230,291 | -11,151,455 |
