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 783,111,805, 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 | 783,111,805 | |
| -1 | -783,111,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 783,111,805.
Example:
1 x 783,111,805 = 783,111,805
and
-1 x -783,111,805 = 783,111,805
Notice both answers equal 783,111,805
With that explanation out of the way, let's continue. Next, we take the number 783,111,805 and divide it by 2:
783,111,805 ÷ 2 = 391,555,902.5
If the quotient is a whole number, then 2 and 391,555,902.5 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 | 783,111,805 | |
| -1 | -783,111,805 |
Now, we try dividing 783,111,805 by 3:
783,111,805 ÷ 3 = 261,037,268.3333
If the quotient is a whole number, then 3 and 261,037,268.3333 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 | 783,111,805 | |
| -1 | -783,111,805 |
Let's try dividing by 4:
783,111,805 ÷ 4 = 195,777,951.25
If the quotient is a whole number, then 4 and 195,777,951.25 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 | 783,111,805 | |
| -1 | 783,111,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 937 | 4,685 | 6,559 | 23,879 | 32,795 | 119,395 | 167,153 | 835,765 | 22,374,623 | 111,873,115 | 156,622,361 | 783,111,805 |
| -1 | -5 | -7 | -35 | -937 | -4,685 | -6,559 | -23,879 | -32,795 | -119,395 | -167,153 | -835,765 | -22,374,623 | -111,873,115 | -156,622,361 | -783,111,805 |
