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 121,554,433, 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 | 121,554,433 | |
| -1 | -121,554,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 121,554,433.
Example:
1 x 121,554,433 = 121,554,433
and
-1 x -121,554,433 = 121,554,433
Notice both answers equal 121,554,433
With that explanation out of the way, let's continue. Next, we take the number 121,554,433 and divide it by 2:
121,554,433 ÷ 2 = 60,777,216.5
If the quotient is a whole number, then 2 and 60,777,216.5 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 | 121,554,433 | |
| -1 | -121,554,433 |
Now, we try dividing 121,554,433 by 3:
121,554,433 ÷ 3 = 40,518,144.3333
If the quotient is a whole number, then 3 and 40,518,144.3333 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 | 121,554,433 | |
| -1 | -121,554,433 |
Let's try dividing by 4:
121,554,433 ÷ 4 = 30,388,608.25
If the quotient is a whole number, then 4 and 30,388,608.25 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 | 121,554,433 | |
| -1 | 121,554,433 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 143 | 169 | 1,001 | 1,183 | 1,859 | 9,341 | 13,013 | 65,387 | 102,751 | 121,433 | 719,257 | 850,031 | 1,335,763 | 1,578,629 | 9,350,341 | 11,050,403 | 17,364,919 | 121,554,433 |
| -1 | -7 | -11 | -13 | -77 | -91 | -143 | -169 | -1,001 | -1,183 | -1,859 | -9,341 | -13,013 | -65,387 | -102,751 | -121,433 | -719,257 | -850,031 | -1,335,763 | -1,578,629 | -9,350,341 | -11,050,403 | -17,364,919 | -121,554,433 |
