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 33,440,771, 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 | 33,440,771 | |
| -1 | -33,440,771 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,440,771.
Example:
1 x 33,440,771 = 33,440,771
and
-1 x -33,440,771 = 33,440,771
Notice both answers equal 33,440,771
With that explanation out of the way, let's continue. Next, we take the number 33,440,771 and divide it by 2:
33,440,771 ÷ 2 = 16,720,385.5
If the quotient is a whole number, then 2 and 16,720,385.5 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 | 33,440,771 | |
| -1 | -33,440,771 |
Now, we try dividing 33,440,771 by 3:
33,440,771 ÷ 3 = 11,146,923.6667
If the quotient is a whole number, then 3 and 11,146,923.6667 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 | 33,440,771 | |
| -1 | -33,440,771 |
Let's try dividing by 4:
33,440,771 ÷ 4 = 8,360,192.75
If the quotient is a whole number, then 4 and 8,360,192.75 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 | 33,440,771 | |
| -1 | 33,440,771 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 89 | 91 | 623 | 1,157 | 4,129 | 8,099 | 28,903 | 53,677 | 367,481 | 375,739 | 2,572,367 | 4,777,253 | 33,440,771 |
| -1 | -7 | -13 | -89 | -91 | -623 | -1,157 | -4,129 | -8,099 | -28,903 | -53,677 | -367,481 | -375,739 | -2,572,367 | -4,777,253 | -33,440,771 |
