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 121,103,101, 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 | 121,103,101 | |
| -1 | -121,103,101 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 121,103,101.
Example:
1 x 121,103,101 = 121,103,101
and
-1 x -121,103,101 = 121,103,101
Notice both answers equal 121,103,101
With that explanation out of the way, let's continue. Next, we take the number 121,103,101 and divide it by 2:
121,103,101 ÷ 2 = 60,551,550.5
If the quotient is a whole number, then 2 and 60,551,550.5 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 | 121,103,101 | |
| -1 | -121,103,101 |
Now, we try dividing 121,103,101 by 3:
121,103,101 ÷ 3 = 40,367,700.3333
If the quotient is a whole number, then 3 and 40,367,700.3333 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 | 121,103,101 | |
| -1 | -121,103,101 |
Let's try dividing by 4:
121,103,101 ÷ 4 = 30,275,775.25
If the quotient is a whole number, then 4 and 30,275,775.25 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 | 121,103,101 | |
| -1 | 121,103,101 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 89 | 203 | 623 | 2,581 | 6,703 | 18,067 | 46,921 | 194,387 | 596,567 | 1,360,709 | 4,175,969 | 17,300,443 | 121,103,101 |
| -1 | -7 | -29 | -89 | -203 | -623 | -2,581 | -6,703 | -18,067 | -46,921 | -194,387 | -596,567 | -1,360,709 | -4,175,969 | -17,300,443 | -121,103,101 |
