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 33,401,105, 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 | 33,401,105 | |
| -1 | -33,401,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,401,105.
Example:
1 x 33,401,105 = 33,401,105
and
-1 x -33,401,105 = 33,401,105
Notice both answers equal 33,401,105
With that explanation out of the way, let's continue. Next, we take the number 33,401,105 and divide it by 2:
33,401,105 ÷ 2 = 16,700,552.5
If the quotient is a whole number, then 2 and 16,700,552.5 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 | 33,401,105 | |
| -1 | -33,401,105 |
Now, we try dividing 33,401,105 by 3:
33,401,105 ÷ 3 = 11,133,701.6667
If the quotient is a whole number, then 3 and 11,133,701.6667 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 | 33,401,105 | |
| -1 | -33,401,105 |
Let's try dividing by 4:
33,401,105 ÷ 4 = 8,350,276.25
If the quotient is a whole number, then 4 and 8,350,276.25 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 | 33,401,105 | |
| -1 | 33,401,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 113 | 155 | 565 | 1,907 | 3,503 | 9,535 | 17,515 | 59,117 | 215,491 | 295,585 | 1,077,455 | 6,680,221 | 33,401,105 |
| -1 | -5 | -31 | -113 | -155 | -565 | -1,907 | -3,503 | -9,535 | -17,515 | -59,117 | -215,491 | -295,585 | -1,077,455 | -6,680,221 | -33,401,105 |
