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 304,310,747, 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 | 304,310,747 | |
-1 | -304,310,747 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 304,310,747.
Example:
1 x 304,310,747 = 304,310,747
and
-1 x -304,310,747 = 304,310,747
Notice both answers equal 304,310,747
With that explanation out of the way, let's continue. Next, we take the number 304,310,747 and divide it by 2:
304,310,747 ÷ 2 = 152,155,373.5
If the quotient is a whole number, then 2 and 152,155,373.5 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 | 304,310,747 | |
-1 | -304,310,747 |
Now, we try dividing 304,310,747 by 3:
304,310,747 ÷ 3 = 101,436,915.6667
If the quotient is a whole number, then 3 and 101,436,915.6667 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 | 304,310,747 | |
-1 | -304,310,747 |
Let's try dividing by 4:
304,310,747 ÷ 4 = 76,077,686.75
If the quotient is a whole number, then 4 and 76,077,686.75 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 | 304,310,747 | |
-1 | 304,310,747 |
If you did it right, you will end up with this table:
1 | 13 | 23,408,519 | 304,310,747 |
-1 | -13 | -23,408,519 | -304,310,747 |
