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 300,142,091, 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 | 300,142,091 | |
| -1 | -300,142,091 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,142,091.
Example:
1 x 300,142,091 = 300,142,091
and
-1 x -300,142,091 = 300,142,091
Notice both answers equal 300,142,091
With that explanation out of the way, let's continue. Next, we take the number 300,142,091 and divide it by 2:
300,142,091 ÷ 2 = 150,071,045.5
If the quotient is a whole number, then 2 and 150,071,045.5 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 | 300,142,091 | |
| -1 | -300,142,091 |
Now, we try dividing 300,142,091 by 3:
300,142,091 ÷ 3 = 100,047,363.6667
If the quotient is a whole number, then 3 and 100,047,363.6667 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 | 300,142,091 | |
| -1 | -300,142,091 |
Let's try dividing by 4:
300,142,091 ÷ 4 = 75,035,522.75
If the quotient is a whole number, then 4 and 75,035,522.75 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 | 300,142,091 | |
| -1 | 300,142,091 |
If you did it right, you will end up with this table:
| 1 | 131 | 631 | 3,631 | 82,661 | 475,661 | 2,291,161 | 300,142,091 |
| -1 | -131 | -631 | -3,631 | -82,661 | -475,661 | -2,291,161 | -300,142,091 |
