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 305,666,207, 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 | 305,666,207 | |
| -1 | -305,666,207 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 305,666,207.
Example:
1 x 305,666,207 = 305,666,207
and
-1 x -305,666,207 = 305,666,207
Notice both answers equal 305,666,207
With that explanation out of the way, let's continue. Next, we take the number 305,666,207 and divide it by 2:
305,666,207 ÷ 2 = 152,833,103.5
If the quotient is a whole number, then 2 and 152,833,103.5 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 | 305,666,207 | |
| -1 | -305,666,207 |
Now, we try dividing 305,666,207 by 3:
305,666,207 ÷ 3 = 101,888,735.6667
If the quotient is a whole number, then 3 and 101,888,735.6667 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 | 305,666,207 | |
| -1 | -305,666,207 |
Let's try dividing by 4:
305,666,207 ÷ 4 = 76,416,551.75
If the quotient is a whole number, then 4 and 76,416,551.75 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 | 305,666,207 | |
| -1 | 305,666,207 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 121 | 509 | 709 | 847 | 3,563 | 4,963 | 5,599 | 7,799 | 39,193 | 54,593 | 61,589 | 85,789 | 360,881 | 431,123 | 600,523 | 2,526,167 | 3,969,691 | 27,787,837 | 43,666,601 | 305,666,207 |
| -1 | -7 | -11 | -77 | -121 | -509 | -709 | -847 | -3,563 | -4,963 | -5,599 | -7,799 | -39,193 | -54,593 | -61,589 | -85,789 | -360,881 | -431,123 | -600,523 | -2,526,167 | -3,969,691 | -27,787,837 | -43,666,601 | -305,666,207 |
