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 11,151,023, 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 | 11,151,023 | |
| -1 | -11,151,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,151,023.
Example:
1 x 11,151,023 = 11,151,023
and
-1 x -11,151,023 = 11,151,023
Notice both answers equal 11,151,023
With that explanation out of the way, let's continue. Next, we take the number 11,151,023 and divide it by 2:
11,151,023 ÷ 2 = 5,575,511.5
If the quotient is a whole number, then 2 and 5,575,511.5 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 | 11,151,023 | |
| -1 | -11,151,023 |
Now, we try dividing 11,151,023 by 3:
11,151,023 ÷ 3 = 3,717,007.6667
If the quotient is a whole number, then 3 and 3,717,007.6667 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 | 11,151,023 | |
| -1 | -11,151,023 |
Let's try dividing by 4:
11,151,023 ÷ 4 = 2,787,755.75
If the quotient is a whole number, then 4 and 2,787,755.75 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 | 11,151,023 | |
| -1 | 11,151,023 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 97 | 239 | 481 | 1,261 | 3,107 | 3,589 | 8,843 | 23,183 | 46,657 | 114,959 | 301,379 | 857,771 | 11,151,023 |
| -1 | -13 | -37 | -97 | -239 | -481 | -1,261 | -3,107 | -3,589 | -8,843 | -23,183 | -46,657 | -114,959 | -301,379 | -857,771 | -11,151,023 |
