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 66,226,205, 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 | 66,226,205 | |
| -1 | -66,226,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,226,205.
Example:
1 x 66,226,205 = 66,226,205
and
-1 x -66,226,205 = 66,226,205
Notice both answers equal 66,226,205
With that explanation out of the way, let's continue. Next, we take the number 66,226,205 and divide it by 2:
66,226,205 ÷ 2 = 33,113,102.5
If the quotient is a whole number, then 2 and 33,113,102.5 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 | 66,226,205 | |
| -1 | -66,226,205 |
Now, we try dividing 66,226,205 by 3:
66,226,205 ÷ 3 = 22,075,401.6667
If the quotient is a whole number, then 3 and 22,075,401.6667 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 | 66,226,205 | |
| -1 | -66,226,205 |
Let's try dividing by 4:
66,226,205 ÷ 4 = 16,556,551.25
If the quotient is a whole number, then 4 and 16,556,551.25 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 | 66,226,205 | |
| -1 | 66,226,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 199 | 505 | 659 | 995 | 3,295 | 20,099 | 66,559 | 100,495 | 131,141 | 332,795 | 655,705 | 13,245,241 | 66,226,205 |
| -1 | -5 | -101 | -199 | -505 | -659 | -995 | -3,295 | -20,099 | -66,559 | -100,495 | -131,141 | -332,795 | -655,705 | -13,245,241 | -66,226,205 |
