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 41,231,443, 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 | 41,231,443 | |
| -1 | -41,231,443 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,231,443.
Example:
1 x 41,231,443 = 41,231,443
and
-1 x -41,231,443 = 41,231,443
Notice both answers equal 41,231,443
With that explanation out of the way, let's continue. Next, we take the number 41,231,443 and divide it by 2:
41,231,443 ÷ 2 = 20,615,721.5
If the quotient is a whole number, then 2 and 20,615,721.5 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 | 41,231,443 | |
| -1 | -41,231,443 |
Now, we try dividing 41,231,443 by 3:
41,231,443 ÷ 3 = 13,743,814.3333
If the quotient is a whole number, then 3 and 13,743,814.3333 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 | 41,231,443 | |
| -1 | -41,231,443 |
Let's try dividing by 4:
41,231,443 ÷ 4 = 10,307,860.75
If the quotient is a whole number, then 4 and 10,307,860.75 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 | 41,231,443 | |
| -1 | 41,231,443 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 79 | 187 | 869 | 1,343 | 2,791 | 14,773 | 30,701 | 47,447 | 220,489 | 521,917 | 2,425,379 | 3,748,313 | 41,231,443 |
| -1 | -11 | -17 | -79 | -187 | -869 | -1,343 | -2,791 | -14,773 | -30,701 | -47,447 | -220,489 | -521,917 | -2,425,379 | -3,748,313 | -41,231,443 |
