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 40,534,199, 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 | 40,534,199 | |
| -1 | -40,534,199 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 40,534,199.
Example:
1 x 40,534,199 = 40,534,199
and
-1 x -40,534,199 = 40,534,199
Notice both answers equal 40,534,199
With that explanation out of the way, let's continue. Next, we take the number 40,534,199 and divide it by 2:
40,534,199 ÷ 2 = 20,267,099.5
If the quotient is a whole number, then 2 and 20,267,099.5 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 | 40,534,199 | |
| -1 | -40,534,199 |
Now, we try dividing 40,534,199 by 3:
40,534,199 ÷ 3 = 13,511,399.6667
If the quotient is a whole number, then 3 and 13,511,399.6667 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 | 40,534,199 | |
| -1 | -40,534,199 |
Let's try dividing by 4:
40,534,199 ÷ 4 = 10,133,549.75
If the quotient is a whole number, then 4 and 10,133,549.75 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 | 40,534,199 | |
| -1 | 40,534,199 |
If you did it right, you will end up with this table:
| 1 | 29 | 41 | 73 | 467 | 1,189 | 2,117 | 2,993 | 13,543 | 19,147 | 34,091 | 86,797 | 555,263 | 988,639 | 1,397,731 | 40,534,199 |
| -1 | -29 | -41 | -73 | -467 | -1,189 | -2,117 | -2,993 | -13,543 | -19,147 | -34,091 | -86,797 | -555,263 | -988,639 | -1,397,731 | -40,534,199 |
