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 41,635,165, 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 | 41,635,165 | |
| -1 | -41,635,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,635,165.
Example:
1 x 41,635,165 = 41,635,165
and
-1 x -41,635,165 = 41,635,165
Notice both answers equal 41,635,165
With that explanation out of the way, let's continue. Next, we take the number 41,635,165 and divide it by 2:
41,635,165 ÷ 2 = 20,817,582.5
If the quotient is a whole number, then 2 and 20,817,582.5 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 | 41,635,165 | |
| -1 | -41,635,165 |
Now, we try dividing 41,635,165 by 3:
41,635,165 ÷ 3 = 13,878,388.3333
If the quotient is a whole number, then 3 and 13,878,388.3333 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 | 41,635,165 | |
| -1 | -41,635,165 |
Let's try dividing by 4:
41,635,165 ÷ 4 = 10,408,791.25
If the quotient is a whole number, then 4 and 10,408,791.25 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 | 41,635,165 | |
| -1 | 41,635,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 58,231 | 291,155 | 640,541 | 757,003 | 3,202,705 | 3,785,015 | 8,327,033 | 41,635,165 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -58,231 | -291,155 | -640,541 | -757,003 | -3,202,705 | -3,785,015 | -8,327,033 | -41,635,165 |
