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 33,410,729, 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 | 33,410,729 | |
| -1 | -33,410,729 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,410,729.
Example:
1 x 33,410,729 = 33,410,729
and
-1 x -33,410,729 = 33,410,729
Notice both answers equal 33,410,729
With that explanation out of the way, let's continue. Next, we take the number 33,410,729 and divide it by 2:
33,410,729 ÷ 2 = 16,705,364.5
If the quotient is a whole number, then 2 and 16,705,364.5 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 | 33,410,729 | |
| -1 | -33,410,729 |
Now, we try dividing 33,410,729 by 3:
33,410,729 ÷ 3 = 11,136,909.6667
If the quotient is a whole number, then 3 and 11,136,909.6667 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 | 33,410,729 | |
| -1 | -33,410,729 |
Let's try dividing by 4:
33,410,729 ÷ 4 = 8,352,682.25
If the quotient is a whole number, then 4 and 8,352,682.25 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 | 33,410,729 | |
| -1 | 33,410,729 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 373 | 479 | 4,103 | 5,269 | 6,341 | 8,143 | 69,751 | 89,573 | 178,667 | 1,965,337 | 3,037,339 | 33,410,729 |
| -1 | -11 | -17 | -187 | -373 | -479 | -4,103 | -5,269 | -6,341 | -8,143 | -69,751 | -89,573 | -178,667 | -1,965,337 | -3,037,339 | -33,410,729 |
