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 107,776,823, 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 | 107,776,823 | |
| -1 | -107,776,823 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 107,776,823.
Example:
1 x 107,776,823 = 107,776,823
and
-1 x -107,776,823 = 107,776,823
Notice both answers equal 107,776,823
With that explanation out of the way, let's continue. Next, we take the number 107,776,823 and divide it by 2:
107,776,823 ÷ 2 = 53,888,411.5
If the quotient is a whole number, then 2 and 53,888,411.5 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 | 107,776,823 | |
| -1 | -107,776,823 |
Now, we try dividing 107,776,823 by 3:
107,776,823 ÷ 3 = 35,925,607.6667
If the quotient is a whole number, then 3 and 35,925,607.6667 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 | 107,776,823 | |
| -1 | -107,776,823 |
Let's try dividing by 4:
107,776,823 ÷ 4 = 26,944,205.75
If the quotient is a whole number, then 4 and 26,944,205.75 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 | 107,776,823 | |
| -1 | 107,776,823 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 41 | 49 | 77 | 287 | 451 | 539 | 2,009 | 3,157 | 4,877 | 22,099 | 34,139 | 53,647 | 199,957 | 238,973 | 375,529 | 1,399,699 | 2,199,527 | 2,628,703 | 9,797,893 | 15,396,689 | 107,776,823 |
| -1 | -7 | -11 | -41 | -49 | -77 | -287 | -451 | -539 | -2,009 | -3,157 | -4,877 | -22,099 | -34,139 | -53,647 | -199,957 | -238,973 | -375,529 | -1,399,699 | -2,199,527 | -2,628,703 | -9,797,893 | -15,396,689 | -107,776,823 |
