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 41,100,245, 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 | 41,100,245 | |
| -1 | -41,100,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,100,245.
Example:
1 x 41,100,245 = 41,100,245
and
-1 x -41,100,245 = 41,100,245
Notice both answers equal 41,100,245
With that explanation out of the way, let's continue. Next, we take the number 41,100,245 and divide it by 2:
41,100,245 ÷ 2 = 20,550,122.5
If the quotient is a whole number, then 2 and 20,550,122.5 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 | 41,100,245 | |
| -1 | -41,100,245 |
Now, we try dividing 41,100,245 by 3:
41,100,245 ÷ 3 = 13,700,081.6667
If the quotient is a whole number, then 3 and 13,700,081.6667 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 | 41,100,245 | |
| -1 | -41,100,245 |
Let's try dividing by 4:
41,100,245 ÷ 4 = 10,275,061.25
If the quotient is a whole number, then 4 and 10,275,061.25 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 | 41,100,245 | |
| -1 | 41,100,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 157 | 205 | 785 | 1,277 | 6,385 | 6,437 | 32,185 | 52,357 | 200,489 | 261,785 | 1,002,445 | 8,220,049 | 41,100,245 |
| -1 | -5 | -41 | -157 | -205 | -785 | -1,277 | -6,385 | -6,437 | -32,185 | -52,357 | -200,489 | -261,785 | -1,002,445 | -8,220,049 | -41,100,245 |
