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 766,019, 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 | 766,019 | |
-1 | -766,019 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 766,019.
Example:
1 x 766,019 = 766,019
and
-1 x -766,019 = 766,019
Notice both answers equal 766,019
With that explanation out of the way, let's continue. Next, we take the number 766,019 and divide it by 2:
766,019 ÷ 2 = 383,009.5
If the quotient is a whole number, then 2 and 383,009.5 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 | 766,019 | |
-1 | -766,019 |
Now, we try dividing 766,019 by 3:
766,019 ÷ 3 = 255,339.6667
If the quotient is a whole number, then 3 and 255,339.6667 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 | 766,019 | |
-1 | -766,019 |
Let's try dividing by 4:
766,019 ÷ 4 = 191,504.75
If the quotient is a whole number, then 4 and 191,504.75 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 | 766,019 | |
-1 | 766,019 |
If you did it right, you will end up with this table:
1 | 71 | 10,789 | 766,019 |
-1 | -71 | -10,789 | -766,019 |
