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 300,612,715, 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 | 300,612,715 | |
| -1 | -300,612,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,612,715.
Example:
1 x 300,612,715 = 300,612,715
and
-1 x -300,612,715 = 300,612,715
Notice both answers equal 300,612,715
With that explanation out of the way, let's continue. Next, we take the number 300,612,715 and divide it by 2:
300,612,715 ÷ 2 = 150,306,357.5
If the quotient is a whole number, then 2 and 150,306,357.5 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 | 300,612,715 | |
| -1 | -300,612,715 |
Now, we try dividing 300,612,715 by 3:
300,612,715 ÷ 3 = 100,204,238.3333
If the quotient is a whole number, then 3 and 100,204,238.3333 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 | 300,612,715 | |
| -1 | -300,612,715 |
Let's try dividing by 4:
300,612,715 ÷ 4 = 75,153,178.75
If the quotient is a whole number, then 4 and 75,153,178.75 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 | 300,612,715 | |
| -1 | 300,612,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 149 | 745 | 1,937 | 9,685 | 31,039 | 155,195 | 403,507 | 2,017,535 | 4,624,811 | 23,124,055 | 60,122,543 | 300,612,715 |
| -1 | -5 | -13 | -65 | -149 | -745 | -1,937 | -9,685 | -31,039 | -155,195 | -403,507 | -2,017,535 | -4,624,811 | -23,124,055 | -60,122,543 | -300,612,715 |
