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 770,607,673, 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 | 770,607,673 | |
| -1 | -770,607,673 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 770,607,673.
Example:
1 x 770,607,673 = 770,607,673
and
-1 x -770,607,673 = 770,607,673
Notice both answers equal 770,607,673
With that explanation out of the way, let's continue. Next, we take the number 770,607,673 and divide it by 2:
770,607,673 ÷ 2 = 385,303,836.5
If the quotient is a whole number, then 2 and 385,303,836.5 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 | 770,607,673 | |
| -1 | -770,607,673 |
Now, we try dividing 770,607,673 by 3:
770,607,673 ÷ 3 = 256,869,224.3333
If the quotient is a whole number, then 3 and 256,869,224.3333 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 | 770,607,673 | |
| -1 | -770,607,673 |
Let's try dividing by 4:
770,607,673 ÷ 4 = 192,651,918.25
If the quotient is a whole number, then 4 and 192,651,918.25 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 | 770,607,673 | |
| -1 | 770,607,673 |
If you did it right, you will end up with this table:
| 1 | 11 | 59 | 97 | 649 | 1,067 | 5,723 | 12,241 | 62,953 | 134,651 | 722,219 | 1,187,377 | 7,944,409 | 13,061,147 | 70,055,243 | 770,607,673 |
| -1 | -11 | -59 | -97 | -649 | -1,067 | -5,723 | -12,241 | -62,953 | -134,651 | -722,219 | -1,187,377 | -7,944,409 | -13,061,147 | -70,055,243 | -770,607,673 |
