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 11,777,777, 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 | 11,777,777 | |
| -1 | -11,777,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,777,777.
Example:
1 x 11,777,777 = 11,777,777
and
-1 x -11,777,777 = 11,777,777
Notice both answers equal 11,777,777
With that explanation out of the way, let's continue. Next, we take the number 11,777,777 and divide it by 2:
11,777,777 ÷ 2 = 5,888,888.5
If the quotient is a whole number, then 2 and 5,888,888.5 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 | 11,777,777 | |
| -1 | -11,777,777 |
Now, we try dividing 11,777,777 by 3:
11,777,777 ÷ 3 = 3,925,925.6667
If the quotient is a whole number, then 3 and 3,925,925.6667 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 | 11,777,777 | |
| -1 | -11,777,777 |
Let's try dividing by 4:
11,777,777 ÷ 4 = 2,944,444.25
If the quotient is a whole number, then 4 and 2,944,444.25 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 | 11,777,777 | |
| -1 | 11,777,777 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 47 | 109 | 121 | 209 | 517 | 893 | 1,199 | 2,071 | 2,299 | 5,123 | 5,687 | 9,823 | 13,189 | 22,781 | 56,353 | 97,337 | 108,053 | 250,591 | 619,883 | 1,070,707 | 11,777,777 |
| -1 | -11 | -19 | -47 | -109 | -121 | -209 | -517 | -893 | -1,199 | -2,071 | -2,299 | -5,123 | -5,687 | -9,823 | -13,189 | -22,781 | -56,353 | -97,337 | -108,053 | -250,591 | -619,883 | -1,070,707 | -11,777,777 |
