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 773,715,755, 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 | 773,715,755 | |
| -1 | -773,715,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 773,715,755.
Example:
1 x 773,715,755 = 773,715,755
and
-1 x -773,715,755 = 773,715,755
Notice both answers equal 773,715,755
With that explanation out of the way, let's continue. Next, we take the number 773,715,755 and divide it by 2:
773,715,755 ÷ 2 = 386,857,877.5
If the quotient is a whole number, then 2 and 386,857,877.5 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 | 773,715,755 | |
| -1 | -773,715,755 |
Now, we try dividing 773,715,755 by 3:
773,715,755 ÷ 3 = 257,905,251.6667
If the quotient is a whole number, then 3 and 257,905,251.6667 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 | 773,715,755 | |
| -1 | -773,715,755 |
Let's try dividing by 4:
773,715,755 ÷ 4 = 193,428,938.75
If the quotient is a whole number, then 4 and 193,428,938.75 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 | 773,715,755 | |
| -1 | 773,715,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 263 | 355 | 1,315 | 8,287 | 18,673 | 41,435 | 93,365 | 588,377 | 2,179,481 | 2,941,885 | 10,897,405 | 154,743,151 | 773,715,755 |
| -1 | -5 | -71 | -263 | -355 | -1,315 | -8,287 | -18,673 | -41,435 | -93,365 | -588,377 | -2,179,481 | -2,941,885 | -10,897,405 | -154,743,151 | -773,715,755 |
