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 41,178,605, 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 | 41,178,605 | |
| -1 | -41,178,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,178,605.
Example:
1 x 41,178,605 = 41,178,605
and
-1 x -41,178,605 = 41,178,605
Notice both answers equal 41,178,605
With that explanation out of the way, let's continue. Next, we take the number 41,178,605 and divide it by 2:
41,178,605 ÷ 2 = 20,589,302.5
If the quotient is a whole number, then 2 and 20,589,302.5 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 | 41,178,605 | |
| -1 | -41,178,605 |
Now, we try dividing 41,178,605 by 3:
41,178,605 ÷ 3 = 13,726,201.6667
If the quotient is a whole number, then 3 and 13,726,201.6667 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 | 41,178,605 | |
| -1 | -41,178,605 |
Let's try dividing by 4:
41,178,605 ÷ 4 = 10,294,651.25
If the quotient is a whole number, then 4 and 10,294,651.25 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 | 41,178,605 | |
| -1 | 41,178,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 33,343 | 166,715 | 433,459 | 633,517 | 2,167,295 | 3,167,585 | 8,235,721 | 41,178,605 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -33,343 | -166,715 | -433,459 | -633,517 | -2,167,295 | -3,167,585 | -8,235,721 | -41,178,605 |
