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 11,163,145, 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 | 11,163,145 | |
| -1 | -11,163,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,163,145.
Example:
1 x 11,163,145 = 11,163,145
and
-1 x -11,163,145 = 11,163,145
Notice both answers equal 11,163,145
With that explanation out of the way, let's continue. Next, we take the number 11,163,145 and divide it by 2:
11,163,145 ÷ 2 = 5,581,572.5
If the quotient is a whole number, then 2 and 5,581,572.5 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 | 11,163,145 | |
| -1 | -11,163,145 |
Now, we try dividing 11,163,145 by 3:
11,163,145 ÷ 3 = 3,721,048.3333
If the quotient is a whole number, then 3 and 3,721,048.3333 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 | 11,163,145 | |
| -1 | -11,163,145 |
Let's try dividing by 4:
11,163,145 ÷ 4 = 2,790,786.25
If the quotient is a whole number, then 4 and 2,790,786.25 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 | 11,163,145 | |
| -1 | 11,163,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 313 | 1,019 | 1,565 | 2,191 | 5,095 | 7,133 | 10,955 | 35,665 | 318,947 | 1,594,735 | 2,232,629 | 11,163,145 |
| -1 | -5 | -7 | -35 | -313 | -1,019 | -1,565 | -2,191 | -5,095 | -7,133 | -10,955 | -35,665 | -318,947 | -1,594,735 | -2,232,629 | -11,163,145 |
