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 11,101,405, 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 | 11,101,405 | |
| -1 | -11,101,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,101,405.
Example:
1 x 11,101,405 = 11,101,405
and
-1 x -11,101,405 = 11,101,405
Notice both answers equal 11,101,405
With that explanation out of the way, let's continue. Next, we take the number 11,101,405 and divide it by 2:
11,101,405 ÷ 2 = 5,550,702.5
If the quotient is a whole number, then 2 and 5,550,702.5 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 | 11,101,405 | |
| -1 | -11,101,405 |
Now, we try dividing 11,101,405 by 3:
11,101,405 ÷ 3 = 3,700,468.3333
If the quotient is a whole number, then 3 and 3,700,468.3333 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 | 11,101,405 | |
| -1 | -11,101,405 |
Let's try dividing by 4:
11,101,405 ÷ 4 = 2,775,351.25
If the quotient is a whole number, then 4 and 2,775,351.25 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 | 11,101,405 | |
| -1 | 11,101,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 419 | 757 | 2,095 | 2,933 | 3,785 | 5,299 | 14,665 | 26,495 | 317,183 | 1,585,915 | 2,220,281 | 11,101,405 |
| -1 | -5 | -7 | -35 | -419 | -757 | -2,095 | -2,933 | -3,785 | -5,299 | -14,665 | -26,495 | -317,183 | -1,585,915 | -2,220,281 | -11,101,405 |
