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 300,598,661, 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 | 300,598,661 | |
| -1 | -300,598,661 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,598,661.
Example:
1 x 300,598,661 = 300,598,661
and
-1 x -300,598,661 = 300,598,661
Notice both answers equal 300,598,661
With that explanation out of the way, let's continue. Next, we take the number 300,598,661 and divide it by 2:
300,598,661 ÷ 2 = 150,299,330.5
If the quotient is a whole number, then 2 and 150,299,330.5 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 | 300,598,661 | |
| -1 | -300,598,661 |
Now, we try dividing 300,598,661 by 3:
300,598,661 ÷ 3 = 100,199,553.6667
If the quotient is a whole number, then 3 and 100,199,553.6667 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 | 300,598,661 | |
| -1 | -300,598,661 |
Let's try dividing by 4:
300,598,661 ÷ 4 = 75,149,665.25
If the quotient is a whole number, then 4 and 75,149,665.25 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 | 300,598,661 | |
| -1 | 300,598,661 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 31 | 253 | 341 | 713 | 7,843 | 38,327 | 421,597 | 881,521 | 1,188,137 | 9,696,731 | 13,069,507 | 27,327,151 | 300,598,661 |
| -1 | -11 | -23 | -31 | -253 | -341 | -713 | -7,843 | -38,327 | -421,597 | -881,521 | -1,188,137 | -9,696,731 | -13,069,507 | -27,327,151 | -300,598,661 |
