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 41,691,565, 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 | 41,691,565 | |
| -1 | -41,691,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 41,691,565.
Example:
1 x 41,691,565 = 41,691,565
and
-1 x -41,691,565 = 41,691,565
Notice both answers equal 41,691,565
With that explanation out of the way, let's continue. Next, we take the number 41,691,565 and divide it by 2:
41,691,565 ÷ 2 = 20,845,782.5
If the quotient is a whole number, then 2 and 20,845,782.5 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 | 41,691,565 | |
| -1 | -41,691,565 |
Now, we try dividing 41,691,565 by 3:
41,691,565 ÷ 3 = 13,897,188.3333
If the quotient is a whole number, then 3 and 13,897,188.3333 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 | 41,691,565 | |
| -1 | -41,691,565 |
Let's try dividing by 4:
41,691,565 ÷ 4 = 10,422,891.25
If the quotient is a whole number, then 4 and 10,422,891.25 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 | 41,691,565 | |
| -1 | 41,691,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 571 | 859 | 2,855 | 4,295 | 9,707 | 14,603 | 48,535 | 73,015 | 490,489 | 2,452,445 | 8,338,313 | 41,691,565 |
| -1 | -5 | -17 | -85 | -571 | -859 | -2,855 | -4,295 | -9,707 | -14,603 | -48,535 | -73,015 | -490,489 | -2,452,445 | -8,338,313 | -41,691,565 |
