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 756,511, 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 | 756,511 | |
-1 | -756,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 756,511.
Example:
1 x 756,511 = 756,511
and
-1 x -756,511 = 756,511
Notice both answers equal 756,511
With that explanation out of the way, let's continue. Next, we take the number 756,511 and divide it by 2:
756,511 ÷ 2 = 378,255.5
If the quotient is a whole number, then 2 and 378,255.5 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 | 756,511 | |
-1 | -756,511 |
Now, we try dividing 756,511 by 3:
756,511 ÷ 3 = 252,170.3333
If the quotient is a whole number, then 3 and 252,170.3333 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 | 756,511 | |
-1 | -756,511 |
Let's try dividing by 4:
756,511 ÷ 4 = 189,127.75
If the quotient is a whole number, then 4 and 189,127.75 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 | 756,511 | |
-1 | 756,511 |
If you did it right, you will end up with this table:
1 | 7 | 49 | 15,439 | 108,073 | 756,511 |
-1 | -7 | -49 | -15,439 | -108,073 | -756,511 |
