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 784,661,843, 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 | 784,661,843 | |
| -1 | -784,661,843 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 784,661,843.
Example:
1 x 784,661,843 = 784,661,843
and
-1 x -784,661,843 = 784,661,843
Notice both answers equal 784,661,843
With that explanation out of the way, let's continue. Next, we take the number 784,661,843 and divide it by 2:
784,661,843 ÷ 2 = 392,330,921.5
If the quotient is a whole number, then 2 and 392,330,921.5 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 | 784,661,843 | |
| -1 | -784,661,843 |
Now, we try dividing 784,661,843 by 3:
784,661,843 ÷ 3 = 261,553,947.6667
If the quotient is a whole number, then 3 and 261,553,947.6667 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 | 784,661,843 | |
| -1 | -784,661,843 |
Let's try dividing by 4:
784,661,843 ÷ 4 = 196,165,460.75
If the quotient is a whole number, then 4 and 196,165,460.75 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 | 784,661,843 | |
| -1 | 784,661,843 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 49 | 119 | 833 | 941,971 | 6,593,797 | 16,013,507 | 46,156,579 | 112,094,549 | 784,661,843 |
| -1 | -7 | -17 | -49 | -119 | -833 | -941,971 | -6,593,797 | -16,013,507 | -46,156,579 | -112,094,549 | -784,661,843 |
