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 770,540,623, 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 | 770,540,623 | |
| -1 | -770,540,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 770,540,623.
Example:
1 x 770,540,623 = 770,540,623
and
-1 x -770,540,623 = 770,540,623
Notice both answers equal 770,540,623
With that explanation out of the way, let's continue. Next, we take the number 770,540,623 and divide it by 2:
770,540,623 ÷ 2 = 385,270,311.5
If the quotient is a whole number, then 2 and 385,270,311.5 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 | 770,540,623 | |
| -1 | -770,540,623 |
Now, we try dividing 770,540,623 by 3:
770,540,623 ÷ 3 = 256,846,874.3333
If the quotient is a whole number, then 3 and 256,846,874.3333 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 | 770,540,623 | |
| -1 | -770,540,623 |
Let's try dividing by 4:
770,540,623 ÷ 4 = 192,635,155.75
If the quotient is a whole number, then 4 and 192,635,155.75 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 | 770,540,623 | |
| -1 | 770,540,623 |
If you did it right, you will end up with this table:
| 1 | 17 | 73 | 127 | 1,241 | 2,159 | 4,889 | 9,271 | 83,113 | 157,607 | 356,897 | 620,903 | 6,067,249 | 10,555,351 | 45,325,919 | 770,540,623 |
| -1 | -17 | -73 | -127 | -1,241 | -2,159 | -4,889 | -9,271 | -83,113 | -157,607 | -356,897 | -620,903 | -6,067,249 | -10,555,351 | -45,325,919 | -770,540,623 |
