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 33,033,151, 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 | 33,033,151 | |
| -1 | -33,033,151 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,033,151.
Example:
1 x 33,033,151 = 33,033,151
and
-1 x -33,033,151 = 33,033,151
Notice both answers equal 33,033,151
With that explanation out of the way, let's continue. Next, we take the number 33,033,151 and divide it by 2:
33,033,151 ÷ 2 = 16,516,575.5
If the quotient is a whole number, then 2 and 16,516,575.5 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 | 33,033,151 | |
| -1 | -33,033,151 |
Now, we try dividing 33,033,151 by 3:
33,033,151 ÷ 3 = 11,011,050.3333
If the quotient is a whole number, then 3 and 11,011,050.3333 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 | 33,033,151 | |
| -1 | -33,033,151 |
Let's try dividing by 4:
33,033,151 ÷ 4 = 8,258,287.75
If the quotient is a whole number, then 4 and 8,258,287.75 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 | 33,033,151 | |
| -1 | 33,033,151 |
If you did it right, you will end up with this table:
| 1 | 47 | 53 | 89 | 149 | 2,491 | 4,183 | 4,717 | 7,003 | 7,897 | 13,261 | 221,699 | 371,159 | 623,267 | 702,833 | 33,033,151 |
| -1 | -47 | -53 | -89 | -149 | -2,491 | -4,183 | -4,717 | -7,003 | -7,897 | -13,261 | -221,699 | -371,159 | -623,267 | -702,833 | -33,033,151 |
