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 300,213,667, 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 | 300,213,667 | |
| -1 | -300,213,667 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,213,667.
Example:
1 x 300,213,667 = 300,213,667
and
-1 x -300,213,667 = 300,213,667
Notice both answers equal 300,213,667
With that explanation out of the way, let's continue. Next, we take the number 300,213,667 and divide it by 2:
300,213,667 ÷ 2 = 150,106,833.5
If the quotient is a whole number, then 2 and 150,106,833.5 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 | 300,213,667 | |
| -1 | -300,213,667 |
Now, we try dividing 300,213,667 by 3:
300,213,667 ÷ 3 = 100,071,222.3333
If the quotient is a whole number, then 3 and 100,071,222.3333 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 | 300,213,667 | |
| -1 | -300,213,667 |
Let's try dividing by 4:
300,213,667 ÷ 4 = 75,053,416.75
If the quotient is a whole number, then 4 and 75,053,416.75 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 | 300,213,667 | |
| -1 | 300,213,667 |
If you did it right, you will end up with this table:
| 1 | 13 | 67 | 79 | 871 | 1,027 | 4,363 | 5,293 | 56,719 | 68,809 | 292,321 | 344,677 | 3,800,173 | 4,480,801 | 23,093,359 | 300,213,667 |
| -1 | -13 | -67 | -79 | -871 | -1,027 | -4,363 | -5,293 | -56,719 | -68,809 | -292,321 | -344,677 | -3,800,173 | -4,480,801 | -23,093,359 | -300,213,667 |
