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 771,811, 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 | 771,811 | |
-1 | -771,811 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 771,811.
Example:
1 x 771,811 = 771,811
and
-1 x -771,811 = 771,811
Notice both answers equal 771,811
With that explanation out of the way, let's continue. Next, we take the number 771,811 and divide it by 2:
771,811 ÷ 2 = 385,905.5
If the quotient is a whole number, then 2 and 385,905.5 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 | 771,811 | |
-1 | -771,811 |
Now, we try dividing 771,811 by 3:
771,811 ÷ 3 = 257,270.3333
If the quotient is a whole number, then 3 and 257,270.3333 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 | 771,811 | |
-1 | -771,811 |
Let's try dividing by 4:
771,811 ÷ 4 = 192,952.75
If the quotient is a whole number, then 4 and 192,952.75 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 | 771,811 | |
-1 | 771,811 |
If you did it right, you will end up with this table:
1 | 23 | 529 | 1,459 | 33,557 | 771,811 |
-1 | -23 | -529 | -1,459 | -33,557 | -771,811 |
