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 300,616,715, 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 | 300,616,715 | |
| -1 | -300,616,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,616,715.
Example:
1 x 300,616,715 = 300,616,715
and
-1 x -300,616,715 = 300,616,715
Notice both answers equal 300,616,715
With that explanation out of the way, let's continue. Next, we take the number 300,616,715 and divide it by 2:
300,616,715 ÷ 2 = 150,308,357.5
If the quotient is a whole number, then 2 and 150,308,357.5 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 | 300,616,715 | |
| -1 | -300,616,715 |
Now, we try dividing 300,616,715 by 3:
300,616,715 ÷ 3 = 100,205,571.6667
If the quotient is a whole number, then 3 and 100,205,571.6667 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 | 300,616,715 | |
| -1 | -300,616,715 |
Let's try dividing by 4:
300,616,715 ÷ 4 = 75,154,178.75
If the quotient is a whole number, then 4 and 75,154,178.75 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 | 300,616,715 | |
| -1 | 300,616,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 41 | 49 | 205 | 245 | 287 | 1,435 | 2,009 | 10,045 | 29,927 | 149,635 | 209,489 | 1,047,445 | 1,227,007 | 1,466,423 | 6,135,035 | 7,332,115 | 8,589,049 | 42,945,245 | 60,123,343 | 300,616,715 |
| -1 | -5 | -7 | -35 | -41 | -49 | -205 | -245 | -287 | -1,435 | -2,009 | -10,045 | -29,927 | -149,635 | -209,489 | -1,047,445 | -1,227,007 | -1,466,423 | -6,135,035 | -7,332,115 | -8,589,049 | -42,945,245 | -60,123,343 | -300,616,715 |
