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 41,203,115, 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 | 41,203,115 | |
| -1 | -41,203,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,203,115.
Example:
1 x 41,203,115 = 41,203,115
and
-1 x -41,203,115 = 41,203,115
Notice both answers equal 41,203,115
With that explanation out of the way, let's continue. Next, we take the number 41,203,115 and divide it by 2:
41,203,115 ÷ 2 = 20,601,557.5
If the quotient is a whole number, then 2 and 20,601,557.5 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 | 41,203,115 | |
| -1 | -41,203,115 |
Now, we try dividing 41,203,115 by 3:
41,203,115 ÷ 3 = 13,734,371.6667
If the quotient is a whole number, then 3 and 13,734,371.6667 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 | 41,203,115 | |
| -1 | -41,203,115 |
Let's try dividing by 4:
41,203,115 ÷ 4 = 10,300,778.75
If the quotient is a whole number, then 4 and 10,300,778.75 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 | 41,203,115 | |
| -1 | 41,203,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 179 | 895 | 2,423 | 3,401 | 12,115 | 17,005 | 46,037 | 230,185 | 433,717 | 2,168,585 | 8,240,623 | 41,203,115 |
| -1 | -5 | -19 | -95 | -179 | -895 | -2,423 | -3,401 | -12,115 | -17,005 | -46,037 | -230,185 | -433,717 | -2,168,585 | -8,240,623 | -41,203,115 |
