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 770,717,843, 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 | 770,717,843 | |
| -1 | -770,717,843 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 770,717,843.
Example:
1 x 770,717,843 = 770,717,843
and
-1 x -770,717,843 = 770,717,843
Notice both answers equal 770,717,843
With that explanation out of the way, let's continue. Next, we take the number 770,717,843 and divide it by 2:
770,717,843 ÷ 2 = 385,358,921.5
If the quotient is a whole number, then 2 and 385,358,921.5 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 | 770,717,843 | |
| -1 | -770,717,843 |
Now, we try dividing 770,717,843 by 3:
770,717,843 ÷ 3 = 256,905,947.6667
If the quotient is a whole number, then 3 and 256,905,947.6667 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 | 770,717,843 | |
| -1 | -770,717,843 |
Let's try dividing by 4:
770,717,843 ÷ 4 = 192,679,460.75
If the quotient is a whole number, then 4 and 192,679,460.75 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 | 770,717,843 | |
| -1 | 770,717,843 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 911 | 6,361 | 6,377 | 17,309 | 44,527 | 120,859 | 121,163 | 846,013 | 5,794,871 | 40,564,097 | 110,102,549 | 770,717,843 |
| -1 | -7 | -19 | -133 | -911 | -6,361 | -6,377 | -17,309 | -44,527 | -120,859 | -121,163 | -846,013 | -5,794,871 | -40,564,097 | -110,102,549 | -770,717,843 |
