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 771,471,113, 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 | 771,471,113 | |
| -1 | -771,471,113 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 771,471,113.
Example:
1 x 771,471,113 = 771,471,113
and
-1 x -771,471,113 = 771,471,113
Notice both answers equal 771,471,113
With that explanation out of the way, let's continue. Next, we take the number 771,471,113 and divide it by 2:
771,471,113 ÷ 2 = 385,735,556.5
If the quotient is a whole number, then 2 and 385,735,556.5 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 | 771,471,113 | |
| -1 | -771,471,113 |
Now, we try dividing 771,471,113 by 3:
771,471,113 ÷ 3 = 257,157,037.6667
If the quotient is a whole number, then 3 and 257,157,037.6667 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 | 771,471,113 | |
| -1 | -771,471,113 |
Let's try dividing by 4:
771,471,113 ÷ 4 = 192,867,778.25
If the quotient is a whole number, then 4 and 192,867,778.25 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 | 771,471,113 | |
| -1 | 771,471,113 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 329 | 853 | 2,749 | 5,971 | 19,243 | 40,091 | 129,203 | 280,637 | 904,421 | 2,344,897 | 16,414,279 | 110,210,159 | 771,471,113 |
| -1 | -7 | -47 | -329 | -853 | -2,749 | -5,971 | -19,243 | -40,091 | -129,203 | -280,637 | -904,421 | -2,344,897 | -16,414,279 | -110,210,159 | -771,471,113 |
