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 11,503,349, 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 | 11,503,349 | |
| -1 | -11,503,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,503,349.
Example:
1 x 11,503,349 = 11,503,349
and
-1 x -11,503,349 = 11,503,349
Notice both answers equal 11,503,349
With that explanation out of the way, let's continue. Next, we take the number 11,503,349 and divide it by 2:
11,503,349 ÷ 2 = 5,751,674.5
If the quotient is a whole number, then 2 and 5,751,674.5 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 | 11,503,349 | |
| -1 | -11,503,349 |
Now, we try dividing 11,503,349 by 3:
11,503,349 ÷ 3 = 3,834,449.6667
If the quotient is a whole number, then 3 and 3,834,449.6667 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 | 11,503,349 | |
| -1 | -11,503,349 |
Let's try dividing by 4:
11,503,349 ÷ 4 = 2,875,837.25
If the quotient is a whole number, then 4 and 2,875,837.25 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 | 11,503,349 | |
| -1 | 11,503,349 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 71 | 103 | 121 | 143 | 781 | 923 | 1,133 | 1,339 | 1,573 | 7,313 | 8,591 | 10,153 | 12,463 | 14,729 | 80,443 | 95,069 | 111,683 | 162,019 | 884,873 | 1,045,759 | 11,503,349 |
| -1 | -11 | -13 | -71 | -103 | -121 | -143 | -781 | -923 | -1,133 | -1,339 | -1,573 | -7,313 | -8,591 | -10,153 | -12,463 | -14,729 | -80,443 | -95,069 | -111,683 | -162,019 | -884,873 | -1,045,759 | -11,503,349 |
