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 41,103,485, 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 | 41,103,485 | |
| -1 | -41,103,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,103,485.
Example:
1 x 41,103,485 = 41,103,485
and
-1 x -41,103,485 = 41,103,485
Notice both answers equal 41,103,485
With that explanation out of the way, let's continue. Next, we take the number 41,103,485 and divide it by 2:
41,103,485 ÷ 2 = 20,551,742.5
If the quotient is a whole number, then 2 and 20,551,742.5 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 | 41,103,485 | |
| -1 | -41,103,485 |
Now, we try dividing 41,103,485 by 3:
41,103,485 ÷ 3 = 13,701,161.6667
If the quotient is a whole number, then 3 and 13,701,161.6667 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 | 41,103,485 | |
| -1 | -41,103,485 |
Let's try dividing by 4:
41,103,485 ÷ 4 = 10,275,871.25
If the quotient is a whole number, then 4 and 10,275,871.25 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 | 41,103,485 | |
| -1 | 41,103,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 43 | 185 | 215 | 1,591 | 5,167 | 7,955 | 25,835 | 191,179 | 222,181 | 955,895 | 1,110,905 | 8,220,697 | 41,103,485 |
| -1 | -5 | -37 | -43 | -185 | -215 | -1,591 | -5,167 | -7,955 | -25,835 | -191,179 | -222,181 | -955,895 | -1,110,905 | -8,220,697 | -41,103,485 |
