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 33,020,449, 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 | 33,020,449 | |
| -1 | -33,020,449 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,020,449.
Example:
1 x 33,020,449 = 33,020,449
and
-1 x -33,020,449 = 33,020,449
Notice both answers equal 33,020,449
With that explanation out of the way, let's continue. Next, we take the number 33,020,449 and divide it by 2:
33,020,449 ÷ 2 = 16,510,224.5
If the quotient is a whole number, then 2 and 16,510,224.5 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 | 33,020,449 | |
| -1 | -33,020,449 |
Now, we try dividing 33,020,449 by 3:
33,020,449 ÷ 3 = 11,006,816.3333
If the quotient is a whole number, then 3 and 11,006,816.3333 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 | 33,020,449 | |
| -1 | -33,020,449 |
Let's try dividing by 4:
33,020,449 ÷ 4 = 8,255,112.25
If the quotient is a whole number, then 4 and 8,255,112.25 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 | 33,020,449 | |
| -1 | 33,020,449 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 97 | 679 | 1,067 | 4,421 | 7,469 | 30,947 | 48,631 | 340,417 | 428,837 | 3,001,859 | 4,717,207 | 33,020,449 |
| -1 | -7 | -11 | -77 | -97 | -679 | -1,067 | -4,421 | -7,469 | -30,947 | -48,631 | -340,417 | -428,837 | -3,001,859 | -4,717,207 | -33,020,449 |
