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 66,741,125, 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 | 66,741,125 | |
| -1 | -66,741,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 66,741,125.
Example:
1 x 66,741,125 = 66,741,125
and
-1 x -66,741,125 = 66,741,125
Notice both answers equal 66,741,125
With that explanation out of the way, let's continue. Next, we take the number 66,741,125 and divide it by 2:
66,741,125 ÷ 2 = 33,370,562.5
If the quotient is a whole number, then 2 and 33,370,562.5 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 | 66,741,125 | |
| -1 | -66,741,125 |
Now, we try dividing 66,741,125 by 3:
66,741,125 ÷ 3 = 22,247,041.6667
If the quotient is a whole number, then 3 and 22,247,041.6667 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 | 66,741,125 | |
| -1 | -66,741,125 |
Let's try dividing by 4:
66,741,125 ÷ 4 = 16,685,281.25
If the quotient is a whole number, then 4 and 16,685,281.25 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 | 66,741,125 | |
| -1 | 66,741,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 1,375 | 48,539 | 242,695 | 533,929 | 1,213,475 | 2,669,645 | 6,067,375 | 13,348,225 | 66,741,125 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -1,375 | -48,539 | -242,695 | -533,929 | -1,213,475 | -2,669,645 | -6,067,375 | -13,348,225 | -66,741,125 |
