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 666,107,699, 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 | 666,107,699 | |
| -1 | -666,107,699 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 666,107,699.
Example:
1 x 666,107,699 = 666,107,699
and
-1 x -666,107,699 = 666,107,699
Notice both answers equal 666,107,699
With that explanation out of the way, let's continue. Next, we take the number 666,107,699 and divide it by 2:
666,107,699 ÷ 2 = 333,053,849.5
If the quotient is a whole number, then 2 and 333,053,849.5 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 | 666,107,699 | |
| -1 | -666,107,699 |
Now, we try dividing 666,107,699 by 3:
666,107,699 ÷ 3 = 222,035,899.6667
If the quotient is a whole number, then 3 and 222,035,899.6667 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 | 666,107,699 | |
| -1 | -666,107,699 |
Let's try dividing by 4:
666,107,699 ÷ 4 = 166,526,924.75
If the quotient is a whole number, then 4 and 166,526,924.75 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 | 666,107,699 | |
| -1 | 666,107,699 |
If you did it right, you will end up with this table:
| 1 | 29 | 59 | 73 | 1,711 | 2,117 | 4,307 | 5,333 | 124,903 | 154,657 | 314,647 | 389,309 | 9,124,763 | 11,289,961 | 22,969,231 | 666,107,699 |
| -1 | -29 | -59 | -73 | -1,711 | -2,117 | -4,307 | -5,333 | -124,903 | -154,657 | -314,647 | -389,309 | -9,124,763 | -11,289,961 | -22,969,231 | -666,107,699 |
