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 41,643,415, 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 | 41,643,415 | |
| -1 | -41,643,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,643,415.
Example:
1 x 41,643,415 = 41,643,415
and
-1 x -41,643,415 = 41,643,415
Notice both answers equal 41,643,415
With that explanation out of the way, let's continue. Next, we take the number 41,643,415 and divide it by 2:
41,643,415 ÷ 2 = 20,821,707.5
If the quotient is a whole number, then 2 and 20,821,707.5 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 | 41,643,415 | |
| -1 | -41,643,415 |
Now, we try dividing 41,643,415 by 3:
41,643,415 ÷ 3 = 13,881,138.3333
If the quotient is a whole number, then 3 and 13,881,138.3333 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 | 41,643,415 | |
| -1 | -41,643,415 |
Let's try dividing by 4:
41,643,415 ÷ 4 = 10,410,853.75
If the quotient is a whole number, then 4 and 10,410,853.75 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 | 41,643,415 | |
| -1 | 41,643,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 103 | 515 | 1,133 | 5,665 | 7,351 | 36,755 | 80,861 | 404,305 | 757,153 | 3,785,765 | 8,328,683 | 41,643,415 |
| -1 | -5 | -11 | -55 | -103 | -515 | -1,133 | -5,665 | -7,351 | -36,755 | -80,861 | -404,305 | -757,153 | -3,785,765 | -8,328,683 | -41,643,415 |
