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 49,015,811, 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 | 49,015,811 | |
| -1 | -49,015,811 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 49,015,811.
Example:
1 x 49,015,811 = 49,015,811
and
-1 x -49,015,811 = 49,015,811
Notice both answers equal 49,015,811
With that explanation out of the way, let's continue. Next, we take the number 49,015,811 and divide it by 2:
49,015,811 ÷ 2 = 24,507,905.5
If the quotient is a whole number, then 2 and 24,507,905.5 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 | 49,015,811 | |
| -1 | -49,015,811 |
Now, we try dividing 49,015,811 by 3:
49,015,811 ÷ 3 = 16,338,603.6667
If the quotient is a whole number, then 3 and 16,338,603.6667 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 | 49,015,811 | |
| -1 | -49,015,811 |
Let's try dividing by 4:
49,015,811 ÷ 4 = 12,253,952.75
If the quotient is a whole number, then 4 and 12,253,952.75 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 | 49,015,811 | |
| -1 | 49,015,811 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 221 | 257 | 863 | 3,341 | 4,369 | 11,219 | 14,671 | 56,797 | 190,723 | 221,791 | 2,883,283 | 3,770,447 | 49,015,811 |
| -1 | -13 | -17 | -221 | -257 | -863 | -3,341 | -4,369 | -11,219 | -14,671 | -56,797 | -190,723 | -221,791 | -2,883,283 | -3,770,447 | -49,015,811 |
