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 11,210,015, 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 | 11,210,015 | |
| -1 | -11,210,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,210,015.
Example:
1 x 11,210,015 = 11,210,015
and
-1 x -11,210,015 = 11,210,015
Notice both answers equal 11,210,015
With that explanation out of the way, let's continue. Next, we take the number 11,210,015 and divide it by 2:
11,210,015 ÷ 2 = 5,605,007.5
If the quotient is a whole number, then 2 and 5,605,007.5 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 | 11,210,015 | |
| -1 | -11,210,015 |
Now, we try dividing 11,210,015 by 3:
11,210,015 ÷ 3 = 3,736,671.6667
If the quotient is a whole number, then 3 and 3,736,671.6667 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 | 11,210,015 | |
| -1 | -11,210,015 |
Let's try dividing by 4:
11,210,015 ÷ 4 = 2,802,503.75
If the quotient is a whole number, then 4 and 2,802,503.75 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 | 11,210,015 | |
| -1 | 11,210,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 149 | 205 | 367 | 745 | 1,835 | 6,109 | 15,047 | 30,545 | 54,683 | 75,235 | 273,415 | 2,242,003 | 11,210,015 |
| -1 | -5 | -41 | -149 | -205 | -367 | -745 | -1,835 | -6,109 | -15,047 | -30,545 | -54,683 | -75,235 | -273,415 | -2,242,003 | -11,210,015 |
