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 33,451,121, 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 | 33,451,121 | |
| -1 | -33,451,121 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,451,121.
Example:
1 x 33,451,121 = 33,451,121
and
-1 x -33,451,121 = 33,451,121
Notice both answers equal 33,451,121
With that explanation out of the way, let's continue. Next, we take the number 33,451,121 and divide it by 2:
33,451,121 ÷ 2 = 16,725,560.5
If the quotient is a whole number, then 2 and 16,725,560.5 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 | 33,451,121 | |
| -1 | -33,451,121 |
Now, we try dividing 33,451,121 by 3:
33,451,121 ÷ 3 = 11,150,373.6667
If the quotient is a whole number, then 3 and 11,150,373.6667 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 | 33,451,121 | |
| -1 | -33,451,121 |
Let's try dividing by 4:
33,451,121 ÷ 4 = 8,362,780.25
If the quotient is a whole number, then 4 and 8,362,780.25 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 | 33,451,121 | |
| -1 | 33,451,121 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 41 | 187 | 451 | 697 | 4,363 | 7,667 | 47,993 | 74,171 | 178,883 | 815,881 | 1,967,713 | 3,041,011 | 33,451,121 |
| -1 | -11 | -17 | -41 | -187 | -451 | -697 | -4,363 | -7,667 | -47,993 | -74,171 | -178,883 | -815,881 | -1,967,713 | -3,041,011 | -33,451,121 |
