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 301,051,511, 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 | 301,051,511 | |
-1 | -301,051,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 301,051,511.
Example:
1 x 301,051,511 = 301,051,511
and
-1 x -301,051,511 = 301,051,511
Notice both answers equal 301,051,511
With that explanation out of the way, let's continue. Next, we take the number 301,051,511 and divide it by 2:
301,051,511 ÷ 2 = 150,525,755.5
If the quotient is a whole number, then 2 and 150,525,755.5 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 | 301,051,511 | |
-1 | -301,051,511 |
Now, we try dividing 301,051,511 by 3:
301,051,511 ÷ 3 = 100,350,503.6667
If the quotient is a whole number, then 3 and 100,350,503.6667 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 | 301,051,511 | |
-1 | -301,051,511 |
Let's try dividing by 4:
301,051,511 ÷ 4 = 75,262,877.75
If the quotient is a whole number, then 4 and 75,262,877.75 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 | 301,051,511 | |
-1 | 301,051,511 |
If you did it right, you will end up with this table:
1 | 12,007 | 25,073 | 301,051,511 |
-1 | -12,007 | -25,073 | -301,051,511 |
