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 11,576,345, 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 | 11,576,345 | |
| -1 | -11,576,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,576,345.
Example:
1 x 11,576,345 = 11,576,345
and
-1 x -11,576,345 = 11,576,345
Notice both answers equal 11,576,345
With that explanation out of the way, let's continue. Next, we take the number 11,576,345 and divide it by 2:
11,576,345 ÷ 2 = 5,788,172.5
If the quotient is a whole number, then 2 and 5,788,172.5 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 | 11,576,345 | |
| -1 | -11,576,345 |
Now, we try dividing 11,576,345 by 3:
11,576,345 ÷ 3 = 3,858,781.6667
If the quotient is a whole number, then 3 and 3,858,781.6667 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 | 11,576,345 | |
| -1 | -11,576,345 |
Let's try dividing by 4:
11,576,345 ÷ 4 = 2,894,086.25
If the quotient is a whole number, then 4 and 2,894,086.25 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 | 11,576,345 | |
| -1 | 11,576,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 109 | 545 | 1,199 | 1,931 | 5,995 | 9,655 | 21,241 | 106,205 | 210,479 | 1,052,395 | 2,315,269 | 11,576,345 |
| -1 | -5 | -11 | -55 | -109 | -545 | -1,199 | -1,931 | -5,995 | -9,655 | -21,241 | -106,205 | -210,479 | -1,052,395 | -2,315,269 | -11,576,345 |
