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 66,660,275, 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 | 66,660,275 | |
| -1 | -66,660,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,660,275.
Example:
1 x 66,660,275 = 66,660,275
and
-1 x -66,660,275 = 66,660,275
Notice both answers equal 66,660,275
With that explanation out of the way, let's continue. Next, we take the number 66,660,275 and divide it by 2:
66,660,275 ÷ 2 = 33,330,137.5
If the quotient is a whole number, then 2 and 33,330,137.5 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 | 66,660,275 | |
| -1 | -66,660,275 |
Now, we try dividing 66,660,275 by 3:
66,660,275 ÷ 3 = 22,220,091.6667
If the quotient is a whole number, then 3 and 22,220,091.6667 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 | 66,660,275 | |
| -1 | -66,660,275 |
Let's try dividing by 4:
66,660,275 ÷ 4 = 16,665,068.75
If the quotient is a whole number, then 4 and 16,665,068.75 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 | 66,660,275 | |
| -1 | 66,660,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 223 | 275 | 1,087 | 1,115 | 2,453 | 5,435 | 5,575 | 11,957 | 12,265 | 27,175 | 59,785 | 61,325 | 242,401 | 298,925 | 1,212,005 | 2,666,411 | 6,060,025 | 13,332,055 | 66,660,275 |
| -1 | -5 | -11 | -25 | -55 | -223 | -275 | -1,087 | -1,115 | -2,453 | -5,435 | -5,575 | -11,957 | -12,265 | -27,175 | -59,785 | -61,325 | -242,401 | -298,925 | -1,212,005 | -2,666,411 | -6,060,025 | -13,332,055 | -66,660,275 |
