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 301,202,459, 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 | 301,202,459 | |
| -1 | -301,202,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 301,202,459.
Example:
1 x 301,202,459 = 301,202,459
and
-1 x -301,202,459 = 301,202,459
Notice both answers equal 301,202,459
With that explanation out of the way, let's continue. Next, we take the number 301,202,459 and divide it by 2:
301,202,459 ÷ 2 = 150,601,229.5
If the quotient is a whole number, then 2 and 150,601,229.5 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 | 301,202,459 | |
| -1 | -301,202,459 |
Now, we try dividing 301,202,459 by 3:
301,202,459 ÷ 3 = 100,400,819.6667
If the quotient is a whole number, then 3 and 100,400,819.6667 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 | 301,202,459 | |
| -1 | -301,202,459 |
Let's try dividing by 4:
301,202,459 ÷ 4 = 75,300,614.75
If the quotient is a whole number, then 4 and 75,300,614.75 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 | 301,202,459 | |
| -1 | 301,202,459 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 157 | 703 | 2,729 | 2,983 | 5,809 | 51,851 | 100,973 | 110,371 | 428,453 | 1,918,487 | 8,140,607 | 15,852,761 | 301,202,459 |
| -1 | -19 | -37 | -157 | -703 | -2,729 | -2,983 | -5,809 | -51,851 | -100,973 | -110,371 | -428,453 | -1,918,487 | -8,140,607 | -15,852,761 | -301,202,459 |
