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 49,916,279, 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 | 49,916,279 | |
| -1 | -49,916,279 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 49,916,279.
Example:
1 x 49,916,279 = 49,916,279
and
-1 x -49,916,279 = 49,916,279
Notice both answers equal 49,916,279
With that explanation out of the way, let's continue. Next, we take the number 49,916,279 and divide it by 2:
49,916,279 ÷ 2 = 24,958,139.5
If the quotient is a whole number, then 2 and 24,958,139.5 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 | 49,916,279 | |
| -1 | -49,916,279 |
Now, we try dividing 49,916,279 by 3:
49,916,279 ÷ 3 = 16,638,759.6667
If the quotient is a whole number, then 3 and 16,638,759.6667 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 | 49,916,279 | |
| -1 | -49,916,279 |
Let's try dividing by 4:
49,916,279 ÷ 4 = 12,479,069.75
If the quotient is a whole number, then 4 and 12,479,069.75 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 | 49,916,279 | |
| -1 | 49,916,279 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 29 | 161 | 203 | 667 | 4,669 | 10,691 | 74,837 | 245,893 | 310,039 | 1,721,251 | 2,170,273 | 7,130,897 | 49,916,279 |
| -1 | -7 | -23 | -29 | -161 | -203 | -667 | -4,669 | -10,691 | -74,837 | -245,893 | -310,039 | -1,721,251 | -2,170,273 | -7,130,897 | -49,916,279 |
