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 303,343,145, 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 | 303,343,145 | |
| -1 | -303,343,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,343,145.
Example:
1 x 303,343,145 = 303,343,145
and
-1 x -303,343,145 = 303,343,145
Notice both answers equal 303,343,145
With that explanation out of the way, let's continue. Next, we take the number 303,343,145 and divide it by 2:
303,343,145 ÷ 2 = 151,671,572.5
If the quotient is a whole number, then 2 and 151,671,572.5 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 | 303,343,145 | |
| -1 | -303,343,145 |
Now, we try dividing 303,343,145 by 3:
303,343,145 ÷ 3 = 101,114,381.6667
If the quotient is a whole number, then 3 and 101,114,381.6667 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 | 303,343,145 | |
| -1 | -303,343,145 |
Let's try dividing by 4:
303,343,145 ÷ 4 = 75,835,786.25
If the quotient is a whole number, then 4 and 75,835,786.25 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 | 303,343,145 | |
| -1 | 303,343,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 151 | 755 | 1,057 | 5,285 | 57,397 | 286,985 | 401,779 | 2,008,895 | 8,666,947 | 43,334,735 | 60,668,629 | 303,343,145 |
| -1 | -5 | -7 | -35 | -151 | -755 | -1,057 | -5,285 | -57,397 | -286,985 | -401,779 | -2,008,895 | -8,666,947 | -43,334,735 | -60,668,629 | -303,343,145 |
