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 784,846,559, 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 | 784,846,559 | |
| -1 | -784,846,559 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 784,846,559.
Example:
1 x 784,846,559 = 784,846,559
and
-1 x -784,846,559 = 784,846,559
Notice both answers equal 784,846,559
With that explanation out of the way, let's continue. Next, we take the number 784,846,559 and divide it by 2:
784,846,559 ÷ 2 = 392,423,279.5
If the quotient is a whole number, then 2 and 392,423,279.5 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 | 784,846,559 | |
| -1 | -784,846,559 |
Now, we try dividing 784,846,559 by 3:
784,846,559 ÷ 3 = 261,615,519.6667
If the quotient is a whole number, then 3 and 261,615,519.6667 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 | 784,846,559 | |
| -1 | -784,846,559 |
Let's try dividing by 4:
784,846,559 ÷ 4 = 196,211,639.75
If the quotient is a whole number, then 4 and 196,211,639.75 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 | 784,846,559 | |
| -1 | 784,846,559 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 137 | 287 | 959 | 5,617 | 19,961 | 39,319 | 139,727 | 818,401 | 2,734,657 | 5,728,807 | 19,142,599 | 112,120,937 | 784,846,559 |
| -1 | -7 | -41 | -137 | -287 | -959 | -5,617 | -19,961 | -39,319 | -139,727 | -818,401 | -2,734,657 | -5,728,807 | -19,142,599 | -112,120,937 | -784,846,559 |
