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 301,103,243, 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 | 301,103,243 | |
| -1 | -301,103,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 301,103,243.
Example:
1 x 301,103,243 = 301,103,243
and
-1 x -301,103,243 = 301,103,243
Notice both answers equal 301,103,243
With that explanation out of the way, let's continue. Next, we take the number 301,103,243 and divide it by 2:
301,103,243 ÷ 2 = 150,551,621.5
If the quotient is a whole number, then 2 and 150,551,621.5 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 | 301,103,243 | |
| -1 | -301,103,243 |
Now, we try dividing 301,103,243 by 3:
301,103,243 ÷ 3 = 100,367,747.6667
If the quotient is a whole number, then 3 and 100,367,747.6667 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 | 301,103,243 | |
| -1 | -301,103,243 |
Let's try dividing by 4:
301,103,243 ÷ 4 = 75,275,810.75
If the quotient is a whole number, then 4 and 75,275,810.75 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 | 301,103,243 | |
| -1 | 301,103,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 107 | 301 | 749 | 4,601 | 9,349 | 32,207 | 65,443 | 402,007 | 1,000,343 | 2,814,049 | 7,002,401 | 43,014,749 | 301,103,243 |
| -1 | -7 | -43 | -107 | -301 | -749 | -4,601 | -9,349 | -32,207 | -65,443 | -402,007 | -1,000,343 | -2,814,049 | -7,002,401 | -43,014,749 | -301,103,243 |
