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 306,275,611, 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 | 306,275,611 | |
| -1 | -306,275,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 306,275,611.
Example:
1 x 306,275,611 = 306,275,611
and
-1 x -306,275,611 = 306,275,611
Notice both answers equal 306,275,611
With that explanation out of the way, let's continue. Next, we take the number 306,275,611 and divide it by 2:
306,275,611 ÷ 2 = 153,137,805.5
If the quotient is a whole number, then 2 and 153,137,805.5 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 | 306,275,611 | |
| -1 | -306,275,611 |
Now, we try dividing 306,275,611 by 3:
306,275,611 ÷ 3 = 102,091,870.3333
If the quotient is a whole number, then 3 and 102,091,870.3333 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 | 306,275,611 | |
| -1 | -306,275,611 |
Let's try dividing by 4:
306,275,611 ÷ 4 = 76,568,902.75
If the quotient is a whole number, then 4 and 76,568,902.75 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 | 306,275,611 | |
| -1 | 306,275,611 |
If you did it right, you will end up with this table:
| 1 | 19 | 71 | 89 | 1,349 | 1,691 | 2,551 | 6,319 | 48,469 | 120,061 | 181,121 | 227,039 | 3,441,299 | 4,313,741 | 16,119,769 | 306,275,611 |
| -1 | -19 | -71 | -89 | -1,349 | -1,691 | -2,551 | -6,319 | -48,469 | -120,061 | -181,121 | -227,039 | -3,441,299 | -4,313,741 | -16,119,769 | -306,275,611 |
