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 303,620,305, 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 | 303,620,305 | |
| -1 | -303,620,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,620,305.
Example:
1 x 303,620,305 = 303,620,305
and
-1 x -303,620,305 = 303,620,305
Notice both answers equal 303,620,305
With that explanation out of the way, let's continue. Next, we take the number 303,620,305 and divide it by 2:
303,620,305 ÷ 2 = 151,810,152.5
If the quotient is a whole number, then 2 and 151,810,152.5 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 | 303,620,305 | |
| -1 | -303,620,305 |
Now, we try dividing 303,620,305 by 3:
303,620,305 ÷ 3 = 101,206,768.3333
If the quotient is a whole number, then 3 and 101,206,768.3333 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 | 303,620,305 | |
| -1 | -303,620,305 |
Let's try dividing by 4:
303,620,305 ÷ 4 = 75,905,076.25
If the quotient is a whole number, then 4 and 75,905,076.25 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 | 303,620,305 | |
| -1 | 303,620,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 79 | 265 | 395 | 4,187 | 14,503 | 20,935 | 72,515 | 768,659 | 1,145,737 | 3,843,295 | 5,728,685 | 60,724,061 | 303,620,305 |
| -1 | -5 | -53 | -79 | -265 | -395 | -4,187 | -14,503 | -20,935 | -72,515 | -768,659 | -1,145,737 | -3,843,295 | -5,728,685 | -60,724,061 | -303,620,305 |
