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 11,104,045, 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 | 11,104,045 | |
| -1 | -11,104,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,104,045.
Example:
1 x 11,104,045 = 11,104,045
and
-1 x -11,104,045 = 11,104,045
Notice both answers equal 11,104,045
With that explanation out of the way, let's continue. Next, we take the number 11,104,045 and divide it by 2:
11,104,045 ÷ 2 = 5,552,022.5
If the quotient is a whole number, then 2 and 5,552,022.5 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 | 11,104,045 | |
| -1 | -11,104,045 |
Now, we try dividing 11,104,045 by 3:
11,104,045 ÷ 3 = 3,701,348.3333
If the quotient is a whole number, then 3 and 3,701,348.3333 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 | 11,104,045 | |
| -1 | -11,104,045 |
Let's try dividing by 4:
11,104,045 ÷ 4 = 2,776,011.25
If the quotient is a whole number, then 4 and 2,776,011.25 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 | 11,104,045 | |
| -1 | 11,104,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 71 | 155 | 355 | 1,009 | 2,201 | 5,045 | 11,005 | 31,279 | 71,639 | 156,395 | 358,195 | 2,220,809 | 11,104,045 |
| -1 | -5 | -31 | -71 | -155 | -355 | -1,009 | -2,201 | -5,045 | -11,005 | -31,279 | -71,639 | -156,395 | -358,195 | -2,220,809 | -11,104,045 |
