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 103,103,329, 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 | 103,103,329 | |
| -1 | -103,103,329 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,103,329.
Example:
1 x 103,103,329 = 103,103,329
and
-1 x -103,103,329 = 103,103,329
Notice both answers equal 103,103,329
With that explanation out of the way, let's continue. Next, we take the number 103,103,329 and divide it by 2:
103,103,329 ÷ 2 = 51,551,664.5
If the quotient is a whole number, then 2 and 51,551,664.5 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 | 103,103,329 | |
| -1 | -103,103,329 |
Now, we try dividing 103,103,329 by 3:
103,103,329 ÷ 3 = 34,367,776.3333
If the quotient is a whole number, then 3 and 34,367,776.3333 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 | 103,103,329 | |
| -1 | -103,103,329 |
Let's try dividing by 4:
103,103,329 ÷ 4 = 25,775,832.25
If the quotient is a whole number, then 4 and 25,775,832.25 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 | 103,103,329 | |
| -1 | 103,103,329 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 173 | 1,211 | 3,287 | 4,481 | 23,009 | 31,367 | 85,139 | 595,973 | 775,213 | 5,426,491 | 14,729,047 | 103,103,329 |
| -1 | -7 | -19 | -133 | -173 | -1,211 | -3,287 | -4,481 | -23,009 | -31,367 | -85,139 | -595,973 | -775,213 | -5,426,491 | -14,729,047 | -103,103,329 |
