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 41,310,415, 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 | 41,310,415 | |
| -1 | -41,310,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,310,415.
Example:
1 x 41,310,415 = 41,310,415
and
-1 x -41,310,415 = 41,310,415
Notice both answers equal 41,310,415
With that explanation out of the way, let's continue. Next, we take the number 41,310,415 and divide it by 2:
41,310,415 ÷ 2 = 20,655,207.5
If the quotient is a whole number, then 2 and 20,655,207.5 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 | 41,310,415 | |
| -1 | -41,310,415 |
Now, we try dividing 41,310,415 by 3:
41,310,415 ÷ 3 = 13,770,138.3333
If the quotient is a whole number, then 3 and 13,770,138.3333 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 | 41,310,415 | |
| -1 | -41,310,415 |
Let's try dividing by 4:
41,310,415 ÷ 4 = 10,327,603.75
If the quotient is a whole number, then 4 and 10,327,603.75 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 | 41,310,415 | |
| -1 | 41,310,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 47 | 115 | 235 | 1,081 | 5,405 | 7,643 | 38,215 | 175,789 | 359,221 | 878,945 | 1,796,105 | 8,262,083 | 41,310,415 |
| -1 | -5 | -23 | -47 | -115 | -235 | -1,081 | -5,405 | -7,643 | -38,215 | -175,789 | -359,221 | -878,945 | -1,796,105 | -8,262,083 | -41,310,415 |
