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 66,297,335, 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 | 66,297,335 | |
| -1 | -66,297,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,297,335.
Example:
1 x 66,297,335 = 66,297,335
and
-1 x -66,297,335 = 66,297,335
Notice both answers equal 66,297,335
With that explanation out of the way, let's continue. Next, we take the number 66,297,335 and divide it by 2:
66,297,335 ÷ 2 = 33,148,667.5
If the quotient is a whole number, then 2 and 33,148,667.5 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 | 66,297,335 | |
| -1 | -66,297,335 |
Now, we try dividing 66,297,335 by 3:
66,297,335 ÷ 3 = 22,099,111.6667
If the quotient is a whole number, then 3 and 22,099,111.6667 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 | 66,297,335 | |
| -1 | -66,297,335 |
Let's try dividing by 4:
66,297,335 ÷ 4 = 16,574,333.75
If the quotient is a whole number, then 4 and 16,574,333.75 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 | 66,297,335 | |
| -1 | 66,297,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 29 | 65 | 145 | 377 | 1,885 | 35,171 | 175,855 | 457,223 | 1,019,959 | 2,286,115 | 5,099,795 | 13,259,467 | 66,297,335 |
| -1 | -5 | -13 | -29 | -65 | -145 | -377 | -1,885 | -35,171 | -175,855 | -457,223 | -1,019,959 | -2,286,115 | -5,099,795 | -13,259,467 | -66,297,335 |
