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 302,300,515, 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 | 302,300,515 | |
| -1 | -302,300,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,300,515.
Example:
1 x 302,300,515 = 302,300,515
and
-1 x -302,300,515 = 302,300,515
Notice both answers equal 302,300,515
With that explanation out of the way, let's continue. Next, we take the number 302,300,515 and divide it by 2:
302,300,515 ÷ 2 = 151,150,257.5
If the quotient is a whole number, then 2 and 151,150,257.5 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 | 302,300,515 | |
| -1 | -302,300,515 |
Now, we try dividing 302,300,515 by 3:
302,300,515 ÷ 3 = 100,766,838.3333
If the quotient is a whole number, then 3 and 100,766,838.3333 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 | 302,300,515 | |
| -1 | -302,300,515 |
Let's try dividing by 4:
302,300,515 ÷ 4 = 75,575,128.75
If the quotient is a whole number, then 4 and 75,575,128.75 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 | 302,300,515 | |
| -1 | 302,300,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 89 | 445 | 979 | 4,895 | 61,757 | 308,785 | 679,327 | 3,396,635 | 5,496,373 | 27,481,865 | 60,460,103 | 302,300,515 |
| -1 | -5 | -11 | -55 | -89 | -445 | -979 | -4,895 | -61,757 | -308,785 | -679,327 | -3,396,635 | -5,496,373 | -27,481,865 | -60,460,103 | -302,300,515 |
