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 303,241,345, 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 | 303,241,345 | |
| -1 | -303,241,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,241,345.
Example:
1 x 303,241,345 = 303,241,345
and
-1 x -303,241,345 = 303,241,345
Notice both answers equal 303,241,345
With that explanation out of the way, let's continue. Next, we take the number 303,241,345 and divide it by 2:
303,241,345 ÷ 2 = 151,620,672.5
If the quotient is a whole number, then 2 and 151,620,672.5 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 | 303,241,345 | |
| -1 | -303,241,345 |
Now, we try dividing 303,241,345 by 3:
303,241,345 ÷ 3 = 101,080,448.3333
If the quotient is a whole number, then 3 and 101,080,448.3333 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 | 303,241,345 | |
| -1 | -303,241,345 |
Let's try dividing by 4:
303,241,345 ÷ 4 = 75,810,336.25
If the quotient is a whole number, then 4 and 75,810,336.25 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 | 303,241,345 | |
| -1 | 303,241,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 233 | 1,165 | 2,563 | 12,815 | 23,663 | 118,315 | 260,293 | 1,301,465 | 5,513,479 | 27,567,395 | 60,648,269 | 303,241,345 |
| -1 | -5 | -11 | -55 | -233 | -1,165 | -2,563 | -12,815 | -23,663 | -118,315 | -260,293 | -1,301,465 | -5,513,479 | -27,567,395 | -60,648,269 | -303,241,345 |
