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 306,450,571, 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 | 306,450,571 | |
-1 | -306,450,571 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,450,571.
Example:
1 x 306,450,571 = 306,450,571
and
-1 x -306,450,571 = 306,450,571
Notice both answers equal 306,450,571
With that explanation out of the way, let's continue. Next, we take the number 306,450,571 and divide it by 2:
306,450,571 ÷ 2 = 153,225,285.5
If the quotient is a whole number, then 2 and 153,225,285.5 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 | 306,450,571 | |
-1 | -306,450,571 |
Now, we try dividing 306,450,571 by 3:
306,450,571 ÷ 3 = 102,150,190.3333
If the quotient is a whole number, then 3 and 102,150,190.3333 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 | 306,450,571 | |
-1 | -306,450,571 |
Let's try dividing by 4:
306,450,571 ÷ 4 = 76,612,642.75
If the quotient is a whole number, then 4 and 76,612,642.75 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 | 306,450,571 | |
-1 | 306,450,571 |
If you did it right, you will end up with this table:
1 | 7 | 43,778,653 | 306,450,571 |
-1 | -7 | -43,778,653 | -306,450,571 |
