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 41,411,215, 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 | 41,411,215 | |
| -1 | -41,411,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,411,215.
Example:
1 x 41,411,215 = 41,411,215
and
-1 x -41,411,215 = 41,411,215
Notice both answers equal 41,411,215
With that explanation out of the way, let's continue. Next, we take the number 41,411,215 and divide it by 2:
41,411,215 ÷ 2 = 20,705,607.5
If the quotient is a whole number, then 2 and 20,705,607.5 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 | 41,411,215 | |
| -1 | -41,411,215 |
Now, we try dividing 41,411,215 by 3:
41,411,215 ÷ 3 = 13,803,738.3333
If the quotient is a whole number, then 3 and 13,803,738.3333 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 | 41,411,215 | |
| -1 | -41,411,215 |
Let's try dividing by 4:
41,411,215 ÷ 4 = 10,352,803.75
If the quotient is a whole number, then 4 and 10,352,803.75 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 | 41,411,215 | |
| -1 | 41,411,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 229 | 295 | 613 | 1,145 | 3,065 | 13,511 | 36,167 | 67,555 | 140,377 | 180,835 | 701,885 | 8,282,243 | 41,411,215 |
| -1 | -5 | -59 | -229 | -295 | -613 | -1,145 | -3,065 | -13,511 | -36,167 | -67,555 | -140,377 | -180,835 | -701,885 | -8,282,243 | -41,411,215 |
