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 66,606,011, 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 | 66,606,011 | |
| -1 | -66,606,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,606,011.
Example:
1 x 66,606,011 = 66,606,011
and
-1 x -66,606,011 = 66,606,011
Notice both answers equal 66,606,011
With that explanation out of the way, let's continue. Next, we take the number 66,606,011 and divide it by 2:
66,606,011 ÷ 2 = 33,303,005.5
If the quotient is a whole number, then 2 and 33,303,005.5 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 | 66,606,011 | |
| -1 | -66,606,011 |
Now, we try dividing 66,606,011 by 3:
66,606,011 ÷ 3 = 22,202,003.6667
If the quotient is a whole number, then 3 and 22,202,003.6667 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 | 66,606,011 | |
| -1 | -66,606,011 |
Let's try dividing by 4:
66,606,011 ÷ 4 = 16,651,502.75
If the quotient is a whole number, then 4 and 16,651,502.75 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 | 66,606,011 | |
| -1 | 66,606,011 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 43 | 899 | 1,247 | 1,333 | 1,723 | 38,657 | 49,967 | 53,413 | 74,089 | 1,548,977 | 2,148,581 | 2,296,759 | 66,606,011 |
| -1 | -29 | -31 | -43 | -899 | -1,247 | -1,333 | -1,723 | -38,657 | -49,967 | -53,413 | -74,089 | -1,548,977 | -2,148,581 | -2,296,759 | -66,606,011 |
