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 300,020,357, 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 | 300,020,357 | |
| -1 | -300,020,357 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,020,357.
Example:
1 x 300,020,357 = 300,020,357
and
-1 x -300,020,357 = 300,020,357
Notice both answers equal 300,020,357
With that explanation out of the way, let's continue. Next, we take the number 300,020,357 and divide it by 2:
300,020,357 ÷ 2 = 150,010,178.5
If the quotient is a whole number, then 2 and 150,010,178.5 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 | 300,020,357 | |
| -1 | -300,020,357 |
Now, we try dividing 300,020,357 by 3:
300,020,357 ÷ 3 = 100,006,785.6667
If the quotient is a whole number, then 3 and 100,006,785.6667 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 | 300,020,357 | |
| -1 | -300,020,357 |
Let's try dividing by 4:
300,020,357 ÷ 4 = 75,005,089.25
If the quotient is a whole number, then 4 and 75,005,089.25 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 | 300,020,357 | |
| -1 | 300,020,357 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 103 | 721 | 1,339 | 9,373 | 32,009 | 224,063 | 416,117 | 2,912,819 | 3,296,927 | 23,078,489 | 42,860,051 | 300,020,357 |
| -1 | -7 | -13 | -91 | -103 | -721 | -1,339 | -9,373 | -32,009 | -224,063 | -416,117 | -2,912,819 | -3,296,927 | -23,078,489 | -42,860,051 | -300,020,357 |
