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 41,153,255, 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 | 41,153,255 | |
| -1 | -41,153,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,153,255.
Example:
1 x 41,153,255 = 41,153,255
and
-1 x -41,153,255 = 41,153,255
Notice both answers equal 41,153,255
With that explanation out of the way, let's continue. Next, we take the number 41,153,255 and divide it by 2:
41,153,255 ÷ 2 = 20,576,627.5
If the quotient is a whole number, then 2 and 20,576,627.5 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 | 41,153,255 | |
| -1 | -41,153,255 |
Now, we try dividing 41,153,255 by 3:
41,153,255 ÷ 3 = 13,717,751.6667
If the quotient is a whole number, then 3 and 13,717,751.6667 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 | 41,153,255 | |
| -1 | -41,153,255 |
Let's try dividing by 4:
41,153,255 ÷ 4 = 10,288,313.75
If the quotient is a whole number, then 4 and 10,288,313.75 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 | 41,153,255 | |
| -1 | 41,153,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 57,557 | 287,785 | 633,127 | 748,241 | 3,165,635 | 3,741,205 | 8,230,651 | 41,153,255 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -57,557 | -287,785 | -633,127 | -748,241 | -3,165,635 | -3,741,205 | -8,230,651 | -41,153,255 |
