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 300,454,015, 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 | 300,454,015 | |
| -1 | -300,454,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,454,015.
Example:
1 x 300,454,015 = 300,454,015
and
-1 x -300,454,015 = 300,454,015
Notice both answers equal 300,454,015
With that explanation out of the way, let's continue. Next, we take the number 300,454,015 and divide it by 2:
300,454,015 ÷ 2 = 150,227,007.5
If the quotient is a whole number, then 2 and 150,227,007.5 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 | 300,454,015 | |
| -1 | -300,454,015 |
Now, we try dividing 300,454,015 by 3:
300,454,015 ÷ 3 = 100,151,338.3333
If the quotient is a whole number, then 3 and 100,151,338.3333 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 | 300,454,015 | |
| -1 | -300,454,015 |
Let's try dividing by 4:
300,454,015 ÷ 4 = 75,113,503.75
If the quotient is a whole number, then 4 and 75,113,503.75 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 | 300,454,015 | |
| -1 | 300,454,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 137 | 155 | 685 | 4,247 | 14,149 | 21,235 | 70,745 | 438,619 | 1,938,413 | 2,193,095 | 9,692,065 | 60,090,803 | 300,454,015 |
| -1 | -5 | -31 | -137 | -155 | -685 | -4,247 | -14,149 | -21,235 | -70,745 | -438,619 | -1,938,413 | -2,193,095 | -9,692,065 | -60,090,803 | -300,454,015 |
