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 777,306,313, 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 | 777,306,313 | |
| -1 | -777,306,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 777,306,313.
Example:
1 x 777,306,313 = 777,306,313
and
-1 x -777,306,313 = 777,306,313
Notice both answers equal 777,306,313
With that explanation out of the way, let's continue. Next, we take the number 777,306,313 and divide it by 2:
777,306,313 ÷ 2 = 388,653,156.5
If the quotient is a whole number, then 2 and 388,653,156.5 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 | 777,306,313 | |
| -1 | -777,306,313 |
Now, we try dividing 777,306,313 by 3:
777,306,313 ÷ 3 = 259,102,104.3333
If the quotient is a whole number, then 3 and 259,102,104.3333 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 | 777,306,313 | |
| -1 | -777,306,313 |
Let's try dividing by 4:
777,306,313 ÷ 4 = 194,326,578.25
If the quotient is a whole number, then 4 and 194,326,578.25 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 | 777,306,313 | |
| -1 | 777,306,313 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 301 | 1,601 | 1,613 | 11,207 | 11,291 | 68,843 | 69,359 | 481,901 | 485,513 | 2,582,413 | 18,076,891 | 111,043,759 | 777,306,313 |
| -1 | -7 | -43 | -301 | -1,601 | -1,613 | -11,207 | -11,291 | -68,843 | -69,359 | -481,901 | -485,513 | -2,582,413 | -18,076,891 | -111,043,759 | -777,306,313 |
