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 764,831, 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 | 764,831 | |
-1 | -764,831 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 764,831.
Example:
1 x 764,831 = 764,831
and
-1 x -764,831 = 764,831
Notice both answers equal 764,831
With that explanation out of the way, let's continue. Next, we take the number 764,831 and divide it by 2:
764,831 ÷ 2 = 382,415.5
If the quotient is a whole number, then 2 and 382,415.5 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 | 764,831 | |
-1 | -764,831 |
Now, we try dividing 764,831 by 3:
764,831 ÷ 3 = 254,943.6667
If the quotient is a whole number, then 3 and 254,943.6667 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 | 764,831 | |
-1 | -764,831 |
Let's try dividing by 4:
764,831 ÷ 4 = 191,207.75
If the quotient is a whole number, then 4 and 191,207.75 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 | 764,831 | |
-1 | 764,831 |
If you did it right, you will end up with this table:
1 | 47 | 16,273 | 764,831 |
-1 | -47 | -16,273 | -764,831 |
