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 11,311,685, 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 | 11,311,685 | |
| -1 | -11,311,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,311,685.
Example:
1 x 11,311,685 = 11,311,685
and
-1 x -11,311,685 = 11,311,685
Notice both answers equal 11,311,685
With that explanation out of the way, let's continue. Next, we take the number 11,311,685 and divide it by 2:
11,311,685 ÷ 2 = 5,655,842.5
If the quotient is a whole number, then 2 and 5,655,842.5 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 | 11,311,685 | |
| -1 | -11,311,685 |
Now, we try dividing 11,311,685 by 3:
11,311,685 ÷ 3 = 3,770,561.6667
If the quotient is a whole number, then 3 and 3,770,561.6667 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 | 11,311,685 | |
| -1 | -11,311,685 |
Let's try dividing by 4:
11,311,685 ÷ 4 = 2,827,921.25
If the quotient is a whole number, then 4 and 2,827,921.25 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 | 11,311,685 | |
| -1 | 11,311,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 121 | 385 | 605 | 847 | 2,671 | 4,235 | 13,355 | 18,697 | 29,381 | 93,485 | 146,905 | 205,667 | 323,191 | 1,028,335 | 1,615,955 | 2,262,337 | 11,311,685 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -121 | -385 | -605 | -847 | -2,671 | -4,235 | -13,355 | -18,697 | -29,381 | -93,485 | -146,905 | -205,667 | -323,191 | -1,028,335 | -1,615,955 | -2,262,337 | -11,311,685 |
