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 305,350,651, 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 | 305,350,651 | |
| -1 | -305,350,651 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 305,350,651.
Example:
1 x 305,350,651 = 305,350,651
and
-1 x -305,350,651 = 305,350,651
Notice both answers equal 305,350,651
With that explanation out of the way, let's continue. Next, we take the number 305,350,651 and divide it by 2:
305,350,651 ÷ 2 = 152,675,325.5
If the quotient is a whole number, then 2 and 152,675,325.5 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 | 305,350,651 | |
| -1 | -305,350,651 |
Now, we try dividing 305,350,651 by 3:
305,350,651 ÷ 3 = 101,783,550.3333
If the quotient is a whole number, then 3 and 101,783,550.3333 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 | 305,350,651 | |
| -1 | -305,350,651 |
Let's try dividing by 4:
305,350,651 ÷ 4 = 76,337,662.75
If the quotient is a whole number, then 4 and 76,337,662.75 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 | 305,350,651 | |
| -1 | 305,350,651 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 131 | 527 | 2,227 | 4,061 | 4,423 | 69,037 | 75,191 | 137,113 | 579,413 | 2,330,921 | 9,850,021 | 17,961,803 | 305,350,651 |
| -1 | -17 | -31 | -131 | -527 | -2,227 | -4,061 | -4,423 | -69,037 | -75,191 | -137,113 | -579,413 | -2,330,921 | -9,850,021 | -17,961,803 | -305,350,651 |
