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 302,176,027, 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 | 302,176,027 | |
| -1 | -302,176,027 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,176,027.
Example:
1 x 302,176,027 = 302,176,027
and
-1 x -302,176,027 = 302,176,027
Notice both answers equal 302,176,027
With that explanation out of the way, let's continue. Next, we take the number 302,176,027 and divide it by 2:
302,176,027 ÷ 2 = 151,088,013.5
If the quotient is a whole number, then 2 and 151,088,013.5 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 | 302,176,027 | |
| -1 | -302,176,027 |
Now, we try dividing 302,176,027 by 3:
302,176,027 ÷ 3 = 100,725,342.3333
If the quotient is a whole number, then 3 and 100,725,342.3333 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 | 302,176,027 | |
| -1 | -302,176,027 |
Let's try dividing by 4:
302,176,027 ÷ 4 = 75,544,006.75
If the quotient is a whole number, then 4 and 75,544,006.75 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 | 302,176,027 | |
| -1 | 302,176,027 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 79 | 1,189 | 2,291 | 3,217 | 3,239 | 93,293 | 93,931 | 131,897 | 254,143 | 3,825,013 | 7,370,147 | 10,419,863 | 302,176,027 |
| -1 | -29 | -41 | -79 | -1,189 | -2,291 | -3,217 | -3,239 | -93,293 | -93,931 | -131,897 | -254,143 | -3,825,013 | -7,370,147 | -10,419,863 | -302,176,027 |
