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 300,521,035, 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 | 300,521,035 | |
| -1 | -300,521,035 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,521,035.
Example:
1 x 300,521,035 = 300,521,035
and
-1 x -300,521,035 = 300,521,035
Notice both answers equal 300,521,035
With that explanation out of the way, let's continue. Next, we take the number 300,521,035 and divide it by 2:
300,521,035 ÷ 2 = 150,260,517.5
If the quotient is a whole number, then 2 and 150,260,517.5 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 | 300,521,035 | |
| -1 | -300,521,035 |
Now, we try dividing 300,521,035 by 3:
300,521,035 ÷ 3 = 100,173,678.3333
If the quotient is a whole number, then 3 and 100,173,678.3333 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 | 300,521,035 | |
| -1 | -300,521,035 |
Let's try dividing by 4:
300,521,035 ÷ 4 = 75,130,258.75
If the quotient is a whole number, then 4 and 75,130,258.75 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 | 300,521,035 | |
| -1 | 300,521,035 |
If you did it right, you will end up with this table:
| 1 | 5 | 97 | 485 | 601 | 1,031 | 3,005 | 5,155 | 58,297 | 100,007 | 291,485 | 500,035 | 619,631 | 3,098,155 | 60,104,207 | 300,521,035 |
| -1 | -5 | -97 | -485 | -601 | -1,031 | -3,005 | -5,155 | -58,297 | -100,007 | -291,485 | -500,035 | -619,631 | -3,098,155 | -60,104,207 | -300,521,035 |
