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 305,850,547, 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 | 305,850,547 | |
| -1 | -305,850,547 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 305,850,547.
Example:
1 x 305,850,547 = 305,850,547
and
-1 x -305,850,547 = 305,850,547
Notice both answers equal 305,850,547
With that explanation out of the way, let's continue. Next, we take the number 305,850,547 and divide it by 2:
305,850,547 ÷ 2 = 152,925,273.5
If the quotient is a whole number, then 2 and 152,925,273.5 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 | 305,850,547 | |
| -1 | -305,850,547 |
Now, we try dividing 305,850,547 by 3:
305,850,547 ÷ 3 = 101,950,182.3333
If the quotient is a whole number, then 3 and 101,950,182.3333 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 | 305,850,547 | |
| -1 | -305,850,547 |
Let's try dividing by 4:
305,850,547 ÷ 4 = 76,462,636.75
If the quotient is a whole number, then 4 and 76,462,636.75 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 | 305,850,547 | |
| -1 | 305,850,547 |
If you did it right, you will end up with this table:
| 1 | 37 | 89 | 131 | 709 | 3,293 | 4,847 | 11,659 | 26,233 | 63,101 | 92,879 | 431,383 | 2,334,737 | 3,436,523 | 8,266,231 | 305,850,547 |
| -1 | -37 | -89 | -131 | -709 | -3,293 | -4,847 | -11,659 | -26,233 | -63,101 | -92,879 | -431,383 | -2,334,737 | -3,436,523 | -8,266,231 | -305,850,547 |
