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 103,030,301, 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 | 103,030,301 | |
| -1 | -103,030,301 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,030,301.
Example:
1 x 103,030,301 = 103,030,301
and
-1 x -103,030,301 = 103,030,301
Notice both answers equal 103,030,301
With that explanation out of the way, let's continue. Next, we take the number 103,030,301 and divide it by 2:
103,030,301 ÷ 2 = 51,515,150.5
If the quotient is a whole number, then 2 and 51,515,150.5 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 | 103,030,301 | |
| -1 | -103,030,301 |
Now, we try dividing 103,030,301 by 3:
103,030,301 ÷ 3 = 34,343,433.6667
If the quotient is a whole number, then 3 and 34,343,433.6667 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 | 103,030,301 | |
| -1 | -103,030,301 |
Let's try dividing by 4:
103,030,301 ÷ 4 = 25,757,575.25
If the quotient is a whole number, then 4 and 25,757,575.25 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 | 103,030,301 | |
| -1 | 103,030,301 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 71 | 319 | 781 | 2,059 | 4,549 | 22,649 | 50,039 | 131,921 | 322,979 | 1,451,131 | 3,552,769 | 9,366,391 | 103,030,301 |
| -1 | -11 | -29 | -71 | -319 | -781 | -2,059 | -4,549 | -22,649 | -50,039 | -131,921 | -322,979 | -1,451,131 | -3,552,769 | -9,366,391 | -103,030,301 |
