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 300,232,015, 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 | 300,232,015 | |
| -1 | -300,232,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,232,015.
Example:
1 x 300,232,015 = 300,232,015
and
-1 x -300,232,015 = 300,232,015
Notice both answers equal 300,232,015
With that explanation out of the way, let's continue. Next, we take the number 300,232,015 and divide it by 2:
300,232,015 ÷ 2 = 150,116,007.5
If the quotient is a whole number, then 2 and 150,116,007.5 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 | 300,232,015 | |
| -1 | -300,232,015 |
Now, we try dividing 300,232,015 by 3:
300,232,015 ÷ 3 = 100,077,338.3333
If the quotient is a whole number, then 3 and 100,077,338.3333 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 | 300,232,015 | |
| -1 | -300,232,015 |
Let's try dividing by 4:
300,232,015 ÷ 4 = 75,058,003.75
If the quotient is a whole number, then 4 and 75,058,003.75 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 | 300,232,015 | |
| -1 | 300,232,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 53 | 95 | 265 | 1,007 | 5,035 | 59,629 | 298,145 | 1,132,951 | 3,160,337 | 5,664,755 | 15,801,685 | 60,046,403 | 300,232,015 |
| -1 | -5 | -19 | -53 | -95 | -265 | -1,007 | -5,035 | -59,629 | -298,145 | -1,132,951 | -3,160,337 | -5,664,755 | -15,801,685 | -60,046,403 | -300,232,015 |
