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 121,034,419, 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 | 121,034,419 | |
| -1 | -121,034,419 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 121,034,419.
Example:
1 x 121,034,419 = 121,034,419
and
-1 x -121,034,419 = 121,034,419
Notice both answers equal 121,034,419
With that explanation out of the way, let's continue. Next, we take the number 121,034,419 and divide it by 2:
121,034,419 ÷ 2 = 60,517,209.5
If the quotient is a whole number, then 2 and 60,517,209.5 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 | 121,034,419 | |
| -1 | -121,034,419 |
Now, we try dividing 121,034,419 by 3:
121,034,419 ÷ 3 = 40,344,806.3333
If the quotient is a whole number, then 3 and 40,344,806.3333 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 | 121,034,419 | |
| -1 | -121,034,419 |
Let's try dividing by 4:
121,034,419 ÷ 4 = 30,258,604.75
If the quotient is a whole number, then 4 and 30,258,604.75 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 | 121,034,419 | |
| -1 | 121,034,419 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 167 | 451 | 1,607 | 1,837 | 6,847 | 17,677 | 65,887 | 75,317 | 268,369 | 724,757 | 2,952,059 | 11,003,129 | 121,034,419 |
| -1 | -11 | -41 | -167 | -451 | -1,607 | -1,837 | -6,847 | -17,677 | -65,887 | -75,317 | -268,369 | -724,757 | -2,952,059 | -11,003,129 | -121,034,419 |
