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 300,302,305, 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 | 300,302,305 | |
| -1 | -300,302,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,302,305.
Example:
1 x 300,302,305 = 300,302,305
and
-1 x -300,302,305 = 300,302,305
Notice both answers equal 300,302,305
With that explanation out of the way, let's continue. Next, we take the number 300,302,305 and divide it by 2:
300,302,305 ÷ 2 = 150,151,152.5
If the quotient is a whole number, then 2 and 150,151,152.5 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 | 300,302,305 | |
| -1 | -300,302,305 |
Now, we try dividing 300,302,305 by 3:
300,302,305 ÷ 3 = 100,100,768.3333
If the quotient is a whole number, then 3 and 100,100,768.3333 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 | 300,302,305 | |
| -1 | -300,302,305 |
Let's try dividing by 4:
300,302,305 ÷ 4 = 75,075,576.25
If the quotient is a whole number, then 4 and 75,075,576.25 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 | 300,302,305 | |
| -1 | 300,302,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 239 | 395 | 1,195 | 3,181 | 15,905 | 18,881 | 94,405 | 251,299 | 760,259 | 1,256,495 | 3,801,295 | 60,060,461 | 300,302,305 |
| -1 | -5 | -79 | -239 | -395 | -1,195 | -3,181 | -15,905 | -18,881 | -94,405 | -251,299 | -760,259 | -1,256,495 | -3,801,295 | -60,060,461 | -300,302,305 |
