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 41,166,521, 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 | 41,166,521 | |
| -1 | -41,166,521 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,166,521.
Example:
1 x 41,166,521 = 41,166,521
and
-1 x -41,166,521 = 41,166,521
Notice both answers equal 41,166,521
With that explanation out of the way, let's continue. Next, we take the number 41,166,521 and divide it by 2:
41,166,521 ÷ 2 = 20,583,260.5
If the quotient is a whole number, then 2 and 20,583,260.5 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 | 41,166,521 | |
| -1 | -41,166,521 |
Now, we try dividing 41,166,521 by 3:
41,166,521 ÷ 3 = 13,722,173.6667
If the quotient is a whole number, then 3 and 13,722,173.6667 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 | 41,166,521 | |
| -1 | -41,166,521 |
Let's try dividing by 4:
41,166,521 ÷ 4 = 10,291,630.25
If the quotient is a whole number, then 4 and 10,291,630.25 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 | 41,166,521 | |
| -1 | 41,166,521 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 61 | 209 | 671 | 1,159 | 3,229 | 12,749 | 35,519 | 61,351 | 196,969 | 674,861 | 2,166,659 | 3,742,411 | 41,166,521 |
| -1 | -11 | -19 | -61 | -209 | -671 | -1,159 | -3,229 | -12,749 | -35,519 | -61,351 | -196,969 | -674,861 | -2,166,659 | -3,742,411 | -41,166,521 |
