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 11,100,145, 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 | 11,100,145 | |
| -1 | -11,100,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,100,145.
Example:
1 x 11,100,145 = 11,100,145
and
-1 x -11,100,145 = 11,100,145
Notice both answers equal 11,100,145
With that explanation out of the way, let's continue. Next, we take the number 11,100,145 and divide it by 2:
11,100,145 ÷ 2 = 5,550,072.5
If the quotient is a whole number, then 2 and 5,550,072.5 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 | 11,100,145 | |
| -1 | -11,100,145 |
Now, we try dividing 11,100,145 by 3:
11,100,145 ÷ 3 = 3,700,048.3333
If the quotient is a whole number, then 3 and 3,700,048.3333 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 | 11,100,145 | |
| -1 | -11,100,145 |
Let's try dividing by 4:
11,100,145 ÷ 4 = 2,775,036.25
If the quotient is a whole number, then 4 and 2,775,036.25 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 | 11,100,145 | |
| -1 | 11,100,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 23 | 35 | 115 | 161 | 805 | 13,789 | 68,945 | 96,523 | 317,147 | 482,615 | 1,585,735 | 2,220,029 | 11,100,145 |
| -1 | -5 | -7 | -23 | -35 | -115 | -161 | -805 | -13,789 | -68,945 | -96,523 | -317,147 | -482,615 | -1,585,735 | -2,220,029 | -11,100,145 |
