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 303,242,155, 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 | 303,242,155 | |
| -1 | -303,242,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,242,155.
Example:
1 x 303,242,155 = 303,242,155
and
-1 x -303,242,155 = 303,242,155
Notice both answers equal 303,242,155
With that explanation out of the way, let's continue. Next, we take the number 303,242,155 and divide it by 2:
303,242,155 ÷ 2 = 151,621,077.5
If the quotient is a whole number, then 2 and 151,621,077.5 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 | 303,242,155 | |
| -1 | -303,242,155 |
Now, we try dividing 303,242,155 by 3:
303,242,155 ÷ 3 = 101,080,718.3333
If the quotient is a whole number, then 3 and 101,080,718.3333 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 | 303,242,155 | |
| -1 | -303,242,155 |
Let's try dividing by 4:
303,242,155 ÷ 4 = 75,810,538.75
If the quotient is a whole number, then 4 and 75,810,538.75 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 | 303,242,155 | |
| -1 | 303,242,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 1,321 | 1,481 | 6,605 | 7,405 | 40,951 | 45,911 | 204,755 | 229,555 | 1,956,401 | 9,782,005 | 60,648,431 | 303,242,155 |
| -1 | -5 | -31 | -155 | -1,321 | -1,481 | -6,605 | -7,405 | -40,951 | -45,911 | -204,755 | -229,555 | -1,956,401 | -9,782,005 | -60,648,431 | -303,242,155 |
