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 11,270,777, 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 | 11,270,777 | |
| -1 | -11,270,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,270,777.
Example:
1 x 11,270,777 = 11,270,777
and
-1 x -11,270,777 = 11,270,777
Notice both answers equal 11,270,777
With that explanation out of the way, let's continue. Next, we take the number 11,270,777 and divide it by 2:
11,270,777 ÷ 2 = 5,635,388.5
If the quotient is a whole number, then 2 and 5,635,388.5 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 | 11,270,777 | |
| -1 | -11,270,777 |
Now, we try dividing 11,270,777 by 3:
11,270,777 ÷ 3 = 3,756,925.6667
If the quotient is a whole number, then 3 and 3,756,925.6667 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 | 11,270,777 | |
| -1 | -11,270,777 |
Let's try dividing by 4:
11,270,777 ÷ 4 = 2,817,694.25
If the quotient is a whole number, then 4 and 2,817,694.25 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 | 11,270,777 | |
| -1 | 11,270,777 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 173 | 227 | 287 | 1,211 | 1,589 | 7,093 | 9,307 | 39,271 | 49,651 | 65,149 | 274,897 | 1,610,111 | 11,270,777 |
| -1 | -7 | -41 | -173 | -227 | -287 | -1,211 | -1,589 | -7,093 | -9,307 | -39,271 | -49,651 | -65,149 | -274,897 | -1,610,111 | -11,270,777 |
