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 784,471,757, 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 | 784,471,757 | |
-1 | -784,471,757 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 784,471,757.
Example:
1 x 784,471,757 = 784,471,757
and
-1 x -784,471,757 = 784,471,757
Notice both answers equal 784,471,757
With that explanation out of the way, let's continue. Next, we take the number 784,471,757 and divide it by 2:
784,471,757 ÷ 2 = 392,235,878.5
If the quotient is a whole number, then 2 and 392,235,878.5 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 | 784,471,757 | |
-1 | -784,471,757 |
Now, we try dividing 784,471,757 by 3:
784,471,757 ÷ 3 = 261,490,585.6667
If the quotient is a whole number, then 3 and 261,490,585.6667 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 | 784,471,757 | |
-1 | -784,471,757 |
Let's try dividing by 4:
784,471,757 ÷ 4 = 196,117,939.25
If the quotient is a whole number, then 4 and 196,117,939.25 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 | 784,471,757 | |
-1 | 784,471,757 |
If you did it right, you will end up with this table:
1 | 10,799 | 72,643 | 784,471,757 |
-1 | -10,799 | -72,643 | -784,471,757 |
