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 33,668,551, 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 | 33,668,551 | |
| -1 | -33,668,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,668,551.
Example:
1 x 33,668,551 = 33,668,551
and
-1 x -33,668,551 = 33,668,551
Notice both answers equal 33,668,551
With that explanation out of the way, let's continue. Next, we take the number 33,668,551 and divide it by 2:
33,668,551 ÷ 2 = 16,834,275.5
If the quotient is a whole number, then 2 and 16,834,275.5 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 | 33,668,551 | |
| -1 | -33,668,551 |
Now, we try dividing 33,668,551 by 3:
33,668,551 ÷ 3 = 11,222,850.3333
If the quotient is a whole number, then 3 and 11,222,850.3333 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 | 33,668,551 | |
| -1 | -33,668,551 |
Let's try dividing by 4:
33,668,551 ÷ 4 = 8,417,137.75
If the quotient is a whole number, then 4 and 8,417,137.75 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 | 33,668,551 | |
| -1 | 33,668,551 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 119 | 133 | 323 | 2,261 | 14,891 | 104,237 | 253,147 | 282,929 | 1,772,029 | 1,980,503 | 4,809,793 | 33,668,551 |
| -1 | -7 | -17 | -19 | -119 | -133 | -323 | -2,261 | -14,891 | -104,237 | -253,147 | -282,929 | -1,772,029 | -1,980,503 | -4,809,793 | -33,668,551 |
